Since the completion of the 10 yeast cells - based on different mutants and environmental conditions as studied by Zach Wilson - they have been on tour. Their first stop was Molecular, Cellular, Developmental Biology department retreat where students show their current work during two nights of poster presentation. When the yeast cells made their debut they received a high amount of attention from other graduate students curious about the visual forms and the science behind them. Some viewers stayed for 30 min trying to puzzle their way through the science and what each piece of data was telling them - much like Zach's own research process.

The cells second stop was a joint lab meeting (photo above) where Zach featured the yeast cells as a part of his talk about his research progress. He used them as a way to facilitate conversation amongst the labs and encourage group members to try to recreate a circuit diagram that described interactions between the a vacuole membrane lipid (PI3,5P2), a vacuole ion channel and pump, which helped to understand the lipid's function to regulate the cells water and ion concentrations.

The third stop on the yeast cell tour was the Annual Rocky Mountain Yeast Meeting held at the Coors Brewery. This time we tried a different set-up where the lanterns were hung on the wall instead of splayed out on a table. In part this was to match the format and spacing of the poster presentation. People's interest was peaked by the different display of information and many people stayed to investigate the lanterns and try to once again work through the science to see if they would come to a similar conclusion as Zach.

At the Yeast Meeting event there were several suggestions and questions we encountered which led to some slight redesign of the lantern lighting. For example, Zach's advisor suggested that we time the rates to all start together so that you could compare which rates were longest and shortest. Using the micro:bit radio function this was an easy fix. We also experimented with different color ranges to show high and low potassium concentration rather than brightness. We found viewers had a hard time distinguishing between higher and lower potassium concentrations. ​We implemented these changes and then submitted the yeast cells for a campus wide data visualization contest that the Norlin Library was putting on.

The Luminous Yeast project received second place in the campus wide competition and are currently residing in the 2nd floor of the Norlin Library (as shown above). Patrons of the library are instructed to peer inside and try to figure out the story of Zach's research - and to see what conclusions they arrive at. You can see an article about the competition here.

These are the costume sketches. AS you might notice, there are some fairly significant changes in certain outfits between what I sketched and what I will be creating as of this moment. ​There are also a few costumes missing; mainly the Blues and Hip Hop dancers. For these costumes, I already had a pretty clear idea of what I wanted them to look like, and functionality wasn't as much of a problem as it was for dancers. For example, with the aerialist, I had to think of both how to expose the areas in contact with the trapeze most (so no electronics are there), while also making the costume work for more hip focused styles. 

​These are the costumes from the sketches above. Each design choice has an explanation in the chart below. The yellow dots are LEDs. (; 

​So far, I have done a lot of ordering of stuff. I also made a skirt! I wanted to test a new technique, specifically for the swing dancer costume, but also for future pieces, of creating mesh piping to sew around hems that encase neopixels. Since this is a costume rather than an everyday garment, the LEDs don't need to be quite as obtrusively hidden. In the mesh, they are partially, but not entirely hidden from view. 

THe other part about the real world progress is that I am trying not to sew as many of the garments by hand this time. Some costumes will be mostly hand sewn, but I am trying to find better ways to incorporate electronics into ready-made clothes. 

​This code is supposed to use two Microbits, communicating with radio singles, light neopixels based on their proximity. Right now, this is technically working but will require more fiddling before it is exactly what I want it to be. The signal readings that the brightness respond to are a little in consistent, and I am trying to make the whole thing more smooth.

​For this one, at this point, this is just test code. I was tiring to get the compass to work, and it doesn't work all that well, to fill bars on the MicroBit based on where you are facing when turning in a circle. It didn't work, but after more fiddling, we learned that it is because the Microbit's compass readings are about 30 degrees off in random directions for no apparent reason. We (Kari and I) used an iPhone compass pointing in the same direction as the Microbit, and the Microbit was consistently off.

Since early January, Zach Wilson and Lila Finch have been collaborating to think about new ways of communicating with and about science. Zach is a sixth year PhD student in the Molecular, Cellular, and Developmental Biology (MCDB) program and Lila is a second year PhD student in the ATLAS program and a member of the LPC. Zach studies a lipid, called PI(3,5)P2, in the vacuoles of yeast cells. His research is focused on how this lipid controls ion transport at vacuoles to regulate the size, function, and water levels in vacuoles. While his research is performed in yeast, he is currently connecting his discoveries to how plants react to environmental stresses, like high salinity in the soil.

The work together has been about finding new ways to tell the story of Zach's data in ways that have the potential to create new conversations and produce new interactions between the scientist and audience. Through the process of designing and making the artistic representations of the science story, Zach and Lila are examining how knowledge sharing between the two occurs, how it pushes each of them to think about their work in new ways and/or communicate with colleagues, and are curious how the work is used/discussed in different settings (e.g. a scientific poster conference vs. an art gallery vs. a museum space). Below is a little cartoon of the process Zach and Lila went through to arrive at a new representation.

Zach and Lila decided the representational form should be lanterns with which the audience could interact with to make discoveries on their own, whether Zach was there to explain or not. They wanted to have the representations be based in data collected by Zach, so that he could tell the same story he normally does, but in the hopes that the audience would lead themselves through that story by asking him questions. They decided to place a viewing hole in each lantern where a viewer could peer inside of the lantern to get a feel for the types of data that Zach sees and draw conclusions about the relationships between the lights and size; almost being able to explore the correlations Zach has found, without necessarily knowing the meaning. Zach and Lila wanted the lanterns to be able to be used in different contexts, for a scientific presentation or in an art gallery or museum space - where without the context that these are wild type and mutant yeast cells, a viewer could still spend time imagining a story this representation tells.

After deciding on lanterns as the representational form to try out, Lila and Zach have been constructing lanterns that are based in the data Zach has collected for his dissertation. To begin they wanted to make one lantern showing a cell with a vacuole inside that would be able to expand and contract based on different conditions or show different mutant variations. However, because they also wanted the audience to be able to see inside the cell and for there to be multiple cells for more audience members to interact with, they settled on the idea to create one lantern for every mutant Zach has found important to his story, and wild type cells under different conditions. Because the initial idea was to have the lantern expand they settled on latex as the medium to cover the lanterns. Here are some images of a first trial lantern and the process.

Both Zach and Lila felt the latex did not provide any additional purpose besides feeling a bit like skin and did not hold together well, so they decided to instead cover the lanterns in paper, a medium Lila is more familiar with. Below are images of the next trial with paper which they decided was better. The images are from two almost complete lanterns.

These lanterns represent several aspects of Zach's data - including cell size (external size), vacuole size (internal object size), vacuole numbers (nubs on internal structure), lipid number (orange lights), potassium levels in the cell (blue lights), and growth rate (speed of movement of white lights). Each lantern uses a micro:bit to drive the lights. The video below shows the lanterns in a little more detail and the movement of white light indicating growth rate.

Not only do these two lanterns in the video still need to be painted on the outside, when complete there should be a total of 10 lanterns. Only eight more to go!

This past spring semester, for Danielle Szafir's Information Visualization final project, our group decided to make a data physicalization of world happiness data. This interactive sculpture visualized and allowed viewers to explore data from the 2016 World Happiness Report, which ranked 156 countries by their happiness. Happiness scores were determined by surveys collected about individual's life satisfaction in relation to other factors such as health and income. 

We decided to use a somewhat traditional form of an ordered bar graph to indicate the overall happiness score for each represented country. The interactivity came by selecting or de-selecting regions of the world (by pressing that region) and in doing so activating or deactivating the lights for those countries. In that way a viewer could narrow down the region of the world they were most interested in by deselecting other regions of the world. Additionally, factors affecting a countries happiness could be examined by pressing attribute buttons for GDP per capita, family, life expectancy, freedom, government trust, or generosity. When the attribute factors were pressed (only one could be selected at a time) then the map showed a color scale of high (orange) to low (blue) for that countries ranking of that attribute. The video below shows how this visualization could be used.

It was an all hands on deck type of project using all of our skills and talents to pull together such a large artifact! The project consisted of over 300 individually addressable LEDs and 18 micro:bit microcontrollers, along with a massive 4'x8' sheet of particle board with a CNC engraved and cut map of the world. Every bar for each country was individually cut, had lights glued inside and was papered over the outside with a label so it would glow when selected. Here are some pictures of our process.

The project went through many rounds of design before we settled on the map and bar structure - from human sized bars you could crawl on to a game of sliders where you physically moved the happiness bars of each country until you got them all correct. But even once the format was decided upon, programming the LEDs and getting the interactivity went through several iterations. The video below shows the programming structure of how the buttons worked in the final format, however at this point we thought we were going to use brightness for the amount of each attribute and color for the different attributes. We found (as you will see in the video) that the brightness was too hard for our eyes to distinguish, so we went with a color scale in the final product. This video does show how the 18 devices communicated and interacted with one another.

Although the map had a long life in the ATLAS lobby, it has just been deconstructed and its parts cannibalized to be reused in new projects! 

This week Emily and Lila chose the aesthetic theme of squares. Again one person designed the outline of the puzzle, while the other designed the pieces of the puzzle. Then both, using the puzzle design and aesthetic choice, collected data that was inspired by squares. Here are the creations from week two.

This week Emily....

Lila on the other hand used a different technique of data collection and self-reflection to make her puzzle. Inspired by squares, she chose to use the number of right and left turns from a single day, between leaving for work and arriving back home. Instead of taking physical notes, she used it as a mindfulness activity, mentally remembering the paths she walked. Then the following day she mentally retraced her steps noting all the right and left turns both walking and driving. She then translated that into squares where three of the same type of turn created a square (arriving back at the original location but facing a different direction). An icon in the center of each square showed the specific path to and from: work, advisor's office, bathroom, Lowes, around the office, post office.

Now that two weeks work of puzzles are complete the puzzles are starting to expand and fit together to make a larger puzzle! Fun to see this taking form!

Your update from the LPC this week is the announcement of a new project by Lila and Emily that incorporates the laser cutter, data collection, and puzzles. The project inspiration came out of a project already started by Lila, a Ph.D student in the ATLAS Technology, Arts and Media program, and a colleague in a different state. In the project, they decide on a location for which they collect data, and then use their individual creativity to manifest that data in a sewn quilt square. The puzzle project that it inspired, turns this model on its head. Lila and Emily decided to make one puzzle a week (each of which fit together) for the rest of the summer to ultimately end up with one large puzzle. The puzzle would be created based on an aesthetic key chosen, such as spirals, rectangles, or lines, and then find data that could be represented well by that aesthetic key and design the puzzle using the aesthetic key. 

In the system decided by Lila and Emily, the first step is choosing the week's aesthetic key. Then, one person would create the outside shape of the puzzle, and pass the file to the other person, then that person would create the puzzle pieces and send it to the first person. Then, each person designs what will go on the puzzle pieces without showing or consulting the other in it is represented past the aesthetic key given at the beginning of the week. Both puzzles then get laser cut and presented, and that is the end of the week! 

For the first week, the aesthetic  key was "spirals" - and Lila and Emily collected data relating to the the aesthetic of spirals. Lila's representation of spirals, began with thinking about driving as spiraling in towards a location, specifically going home and to work. She tracked the presses and releases of the gas, brake, and neither pedal as she drove to (light line) and from work (dark line) and transferred the length of time of each of those presses into spirals (up spiral = gas pedal, down spiral = brake pedal, flat line = neither). 

This past weekend we ran our first workshop making lanterns at the STEAM Fest Family Fun day, put on by the CU Museum of Natural History. The families, a parent and a child, worked to construct a wire and paper lantern (pyramid or cube structures), decorate it, and program LEDs to illuminate the lantern.

During the two 1.5 hr sessions we had ~15 pairs participate. The children were ages 6-13. It was wonderful to see the parent and child work together to design and construct their own unique physical lanterns. Most families created some kind of story with their painting on the outside. One girl painted her and her grandma on the top showing that they were the two making this lantern. Another child took a story she had written about the adventures of four superhero dogs during a different STEAM session earlier in the day, with Myra Makes, and painted images from that onto her lantern.

For nearly all of the participants, the children especially, this was their first experience with programming. Given that we had a very limited time we introduced the micro:bit and some basic blocks for programing the lights. It was fun to see what different LED light patterns the families wanted to try out to illuminate their lantern, such as a rotating rainbow or flashing red lights.

Overall, it was a great workshop and all families took home an individualized lantern. In future workshops we hope to have more work time with the families so we can include data collection and visualization with sensors, thinking about how devices can communicate, and how information from the natural sciences can be investigated with these lantern forms.

The lantern is complete and runs with data!

This was no small task getting the final parts of the lantern functioning properly. The last steps were to collect the data from the garden, query it, and then program the lights to respond to the data. Ben wrote a wonderful database so that now we can collect data from the garden, store it, and query it! Once that was complete we needed to hook up the lights. However, in order to run the database querying we could only light 216 lights, but the tree has 229 nights! Therefore, we had to learn how to use a Arduino mini to run the lights as a "backpack" from the Arduino uno. This was quite complicated, but with help from ajfisher (at about 1am!) we were able to get the mini programmed and the uno directing traffic to the mini. Here is what that looked like!

Finally, the lights were ready to go and could connect to the data. However, the task of deciding how to map the data to the lights and then program that was no small task. I decided to draw on what high school and middle school students would learn about plants. So after reading standards, textbooks, and thinking back to my own studies, I decided to focus on the processes occurring in plants, such as photosynthesis and transpiration. Here is what the final tree looked like from the front and back!

And finally the overall health of the plan can be determined by looking at the face of the "garden spirit". As moisture drops and stays dropped the blue drains out of the face leaving it more red. However, if the plant is also unable to do photosynthesis for a while (no lights is being detected in the garden and/or temperature is too low) then the red also fades out of the face. Therefore, if the plant has little water and little light then the face lights go very dim, showing an unhealthy situation; however if the plant is healthy we should see a nice purple glow! Here are some final pictures of the lantern with data!

After a few late nights of working the papering and painting of the lantern is complete! Here are the time lapses of painting and papering. The paper process just uses simple copier paper with white glue.

And here is the painting process. The painting was the most terrifying part of this whole thing! The black paint (india ink) seemed very final and the paraffin wax is a bit hard to work with as it likes to run and drip a ton. However, I really enjoyed how the project grew and changed with the ink and the wax.

I also had a ton of advice and help when painting the tree. If you watch carefully during the painting of the tree you can see me take several photos and then make a phone call or hop on a Skype call. Through this process my mom and sister were extremely helpful. My sister, Myra Rasmussen, who was the one who worked in Japan on a nebuta lantern with artist Chiba Sakuryu helped to to decide if I had enough black on at various points throughout the process. And my mom was very helpful in deciding how the face should be painted. This is a funny part of the video where you can see after almost every part that I paint on the face I make a phone call - that is to my mother, Coco Forte (thanks mom!!)!

Here are some still photos of the painting process.

In an effort to practice some smaller lantern making, make some that are more portable, and practice the nebuta painting techniques I made three small lanterns for a Denver art show at the Cabal Gallery, Meet Me at the Corner of Art & Science. I started on Monday at about 5pm and worked through several late nights to get them done by 5pm on Friday for the show. 

I tested out some  new lights, which were already pre-wired so that made one step much faster and I also experimented with a few different microcontrollers from the Micro:bit to Raspberry Pi's. I was hoping to make them battery powered but ran into issues with either the Pi's or the lights needing too much power or the Micro:bit not being able to run the lights and use bluetooth at the same time. I ended up settling for using power cords and Raspberry Pi's but will keep trying out the Micro:bit for different projects as it uses so much less power.

Traditionally nebuta lantern making is started with black outlines, followed by wax (to allow more light through those parts) to create highlights, and finally colored paint is added to the lanterns. Here are some photos of my sister, Myra Rasmussen, working on a float for the nebuta lantern in Amori, Japan. You can see some of this process in these photos, which are courtesy of my sister (she is in the third image).
