For the moving parts weekly challenge. 31 frames, 15 colors counting transparency.
This is my second gif; I used a different program from last time, GIMP, which took some work to figure out. I think there's a lot more that could be done with this piece, but I'm out of time and I'm not certain what I want. Maybe you guys could make your own cool modifications and just use this as your base. : o
Edit: Thanks for the encouragement; there are now eyes!
