Hello all,
I recently discovered www.boxcard2d.com, an interesting project in genetic
algorithms and car design,
and decided I wanted to port it into Racket. However, I seem to have run

It's diverged a bit from where Chipmunk is right now, but it's a
pretty straight-forward FFI, so you should be able to update it (and
if you do, I'll update the package.) The biggest problem with it is
that it doesn't "feel" like Racket when you use it because the
interface is so imperative. Nevert
