I've been working on making pygame on pypy work better. PyPy is a JIT for python that allows you to write python code that runs almost as fast as C (or sometimes faster).

Now it's mostly working(only a few test cases are still failing), but every game I've tried is now working.

Seeing some very nice speeds in pure python code. A 3D raytracer is running 30x faster. Looking forward to using it in LD to do stuff that's usually impossible to do at speed in python. Brute force algorithms all the way!

More details in the blog post.
