Beyond some basic style variation, I think there's a lot of room for experimentation with shapes and their centers of rotation.

When you're done, I'd love to see it as well, and I'm sure others would - yours was my exact thought when I got to that part!

Right? There's something oddly satisfying about watching The Time Blob.
