An open question to me in making a commitment toward learning PyGTK was its status with OpenGL and PyOpenGL. Turns out the situation looks quite good - in that the developer of gtkglext which is the most active, I think, gtk Opengl extension is also himself the developer of its Python binding PyGtkGLExt. I have it installed and working and it looks quite nice.

I just took a look at the PyGTK 2.0 Tutorial http://www.pygtk.org/pygtk2tutorial/index.html Very encouraging to see that much documentation spelled out in a usable format. However, I'm still curious: do you see PyGTK as a better way to spend your time than with wxPython? Wx has OpenGL bindings as well, has for quite some time. Also, wxPython has that very useful front end: when you download it, you get a huge pile of working code in the form of demos, all wrapped up in a well-organized wx GUI interface. I find that extremely cool. However, since VPython is its own thing, I've never been able to wrap my head around a way to treat VPython from within wx the same way I might treat OpenGL (not that I've done the latter either -- but the demo is persuasive). If wx had some way to establish a VPython window within its own unified event loop, that might lead to a next generation of Pygeo, no? Kirby
