We will again be holding PyGTA at the Linux Caffe @ 7pm this Tuesday. If no one else stands up to suggest a topic I'm thinking I'll discuss/show the OpenGL-ctypes work I've been doing on and off for the past few months. I'll try to get a laptop on which to present it so it can produce a few pretty graphics while we discuss how it's written and why I've gone with a foreign-function interface to replace the SWIG-wrapped one.

Have fun, Mike
