Yes, it is the end of another semester of Mathematics and Digital Art! It was a *very* different semester than the first two, as I have mentioned in previous posts, since I began the semester with Processing right away. There are still a few wrinkles to iron out — for example, we had a lab project on interactivity (involving using key presses to change features of the movie as it is running) which was quite a bit more challenging than I expected it would be. But on the whole, I think it was an improvement.

So in this final post for Fall 2017, I’d like to share some examples of student work. In particular, I’ll look at some examples from the Fractal Movie Project, as well as examples of Final Projects.

Recall that the Fractal Movie Project involves using linear interpolation on the parameters in affine transformations in order to make an animated series of fractal images. One student experimented with a bright color palette against a black background. As the fractal morphed, it actually looked like the red part of the image rotated in three dimensions, even though the affine transformations were only two-dimensional.

Cissy wanted to explore the motion of rain in her movie. Although she began with bright colors on a black background, once she saw her fractal in motion, she decided that more subtle colors on a white background would be better suited to suggest falling raindrops being blown about by the wind.

Sepid also incorporated movement in her movie — she created a rotating galaxy with a color palette inspired by the colors of the Aurora Borealis. In addition, she learned how to use the Minim library so she could incorporate sound into her movie as well. Here is a screen shot from her movie.

Now let’s take a look at a few Final Projects. Recall that these projects were very open-ended so that students could go in a direction of their choice. Some really got into their work, with truly inspirational results. The presentation that Sepid gave at a recent meeting of the Bay Area Mathematical Artists was actually work she was doing on her Final Project (read about it here).

Terry took on an ambitious project. She based her work on a Bridges paper by Adam Colestock, *Let the Numbers Do the Walking: Generating Turtle Dances on the Plane from Integer Sequences* (read the paper here). Terry did have some programming experience coming into the course, and so she decided to code all of Adam’s turtle graphics algorithms from scratch! This was no simple task, but she worked hard and eventually accomplished her goal.

Here is a screen shot from one of her movies; Terry wanted to create an interesting visual effect by overlaying multiple copies of the same turtle path. Since this particular path was not too dense in the plane, she was able to work with thicker lines.

Tera created a movie which involved rotating triangles and moving dots. Her movie had a strong sense of motion, and incorporated a vibrant color palette. She remarked that working with color in this project was both fun and quite challenging. In her words, “Playing nicely with hot pink is not an easy feat.”

I would also like to share the fact that Professor Roza Aceska of Ball State University (Muncie, Indiana) will be teaching a course about digital art next semester using Processing which will be incorporating a lot of my course materials. I am very excited about this! Many faculty who come to my talks say they are interested in teaching such a course, but getting Department Chairs and Deans to approve such courses is sometimes an uphill battle.

Professor Aceska’s course will be a bit different from mine — her course is in the Honors Program, and as such, does not count as a mathematics credit. So she will not have most of the mathematics assignments and quizzes that I had in my course. But she will still be emphasizing the fascinating relationship between mathematics, programming, and art. I hope to write more about her course sometime during the next semester.

One final remark — I am helping to organize a Mathematical Art Exhibition at the Golden Section Meeting of the Mathematical Association of America on February 24, 2018 at the California State University, East Bay. So if you’re reading this and are in the Bay Area and would like to submit some mathematical art for inclusion in our exhibit, please let me know!
