	Mmmm, actually the modified NeHe tutorials that come with PyOpenGL are pretty 
good. Tried those yet? Also check out the OpenGL examples that are included 
with the Pygame docs. Finally, OpenGLContext (which includes the NeHe 
tutorials) is good.

OpenGLContext: http://pyopengl.sourceforge.net/context/documentation.html

You'll definitely want to keep an eye on the PyOpenGL reference itself:
http://pyopengl.sourceforge.net/documentation/index.html

I found that sometimes topics were more clearly understood after looking at 
the reference from the above link and examining the behavior of a given 
command, what params it expects, etc, and noting some of the topics discussed 
within the reference (this can provide helpful clues sometimes when you're a 
bit foggy on something).

The NeHe tutorials and the Pygame OpenGL examples are the main references I 
recall using.....seems like I did reference a few other tutorials and help 
pages, but those two were the main resources. Additionally, just playing with 
the code and seeing what happens can be pretty helpful.

Don't worry about the math stuff, heh.......I don't understand most of the 
math I see in the PyOpenGL reference, and I'm at a loss as to explain how to 
do matrix math (touched on it briefly a few years back in college and 
promptly forgot it all). :) If you're strong on trig and geometry you should 
be fine for most normal stuff.
