thanks! I wanted to stay within the 4-color limitation while keeping the model from blending too much into the background, so I decided a fun way to do this would be to use all four colors in the background equally and kind of make them look like TV static. I made my skybox texture out of a pattern of 1pt diagonal lines, and let the gif rotation add the distortion it wanted.
I attached the texture for download, but here’s a preview if you want to see what I mean:
The jelly wiggled no matter what I did, so I let it make its own decisions in the end :P
