Jiggle

Wobble, too.

Jiggle is a jiggle machine written in C. You tell it the shapes and

engine also has Ruby bindings so, although it may be ugly on the
inside, it’s pretty on the outside. And that’s what counts.

I have plans for the future, but I can’t be bothered to type them out
yet. So there.
