My Kinetic Proto-Type

I had fun doing this project. At first, I was intimidated by After Effects and it was the fear that kept me from jumping in. Thanks to this class I was able to dip my feet in by just an inch. I didn't know that expressions could help out with the workflow of the project. Loop expressions rock!
Anyway, here's my project?:
Sound and Vision:
(Inspired by David Bowie's song, Sound and Vision)
Spin
(I couldn't come up with a clever title for this one and I didn't want to overthink so I thought "Keep it simple, sir!")
Bruh
(This one was an interesting assignment because I had to work with two programs simultaneously. Prior to starting this project I already had some knowledge of Illustrator. This makes me really happy.)
Wassup
(When I first saw this technique I thought I had to mess with the graphic editors. You showed an alternative which is keyframe velocity. I'm excited about what I can apply with it.)
