Make a composition using the animation techniques that is a tribute to John Whitney.>
Create the animation using photographs and a slideshow program with animations

Results:

First image shows circles which rotate around the center at different rates, creating patterns that look like flowers when they are organized
Second image shows circles which move in atom/electron type patterns
The colors of the circles in each image change depending on time/angle

Find a short piece of music (can be any duration as long as there are multiple notes a short snippet, or a long song) and make a composition that is a visual equivalent of that sound.
I chose to visualize Pachelbel's Cannon because this song haunted me as a cellist for quite some time. It's really boring to play, but everyone loves it.

Results:

The circles in the middle of the screen visualize the cello's notes. The origin of the circle moves 1/8 around the circle for each note, and then repeats continually, just like the 2 measures that the poor musician must play over and over.
The squares represent the different violin voices, as clarified by the unique colors.
This started out being run off of a time/sin function, but the recording is not perfectly on time so I spent a great deal of time hand coding trigger time values into each note. As a result, there aren't that many sin/cos functions responsible for the visualization, but the spirit is there

Try to use sin and cos to emulate a natural phenomenon.
Spring:
Storm:

Results:

Modified sin/cos functions similar to the first exercise to create spiral visuals

Extend the xeno / atan2 code, making a creature which follows the mouse

Results:

Took a great deal of effort. Each element uses pushMatrix()/translate()/rotate() because I wanted them to follow at different rates
A ridiculous amount of time went into the tail. I was originally going to use a sign wave, but it looked wrong because tails are fixed at one point. I ended up going back to my civil engineering roots/calling a couple of friends and using a fixed-free beam equation and playing with the Young's Modulus value of the tail to make a realistic movement. To get the movement, the value of the load on the tail changes according to a sign function
You'll also notice that the nose and whiskers twitch. How cute!
