Animated objects!

I'm working on character animations now...

(guns turned off for test). Still needs some work - I need to manually or automatically select the shapes that look good when animated like this, and add more variation to the parameters.
The only problem it feels wrong to shot this stuff... I need to come up with some gameplay that doesn't involve shooting 'em down. Maybe shooting down evil geometric shapes that are trying to eat pretty wiggly fractal shapes...
Any ideas?

A while ago I also made some weird rings


(these will go with scripted levels and sort of physics puzzles, except the laws of physics are of my own making)

Ahh, and I might also make 'em evolve somehow or be editable.
