I'm happy to announce the release of the planar 0.3 2D geometry library for Python. The project, although still under development, already has quite a few useful features. The focus of the library is to provide a clean, simple, documented 2D geometry api, with high performance implementations in both Python and C, available under a liberal license. You can check out the docs and grab it from pypi here: http://pypi.python.org/pypi/planar/0.3 Enjoy. -Casey
