Alright. After working with Gabriel Dube a bit, he figured out what was
keeping pyshaders from running on my computer (Thanks!). Now that this
works, I'm looking more again into the actual how of getting a decent
shader setup working. Most everything I can find regarding gaussian blurs
recommends the use of a two-pass system, blurring the image first
horizontally and then vertically. This seems to necessitate the use of
FBOs. What support exists for using FBOs with pyglet? I've been trying to
get GLETools up and running, but I keep getting the following error when
trying to import it:
Traceback (most recent call last):
File "C:\Users\Erik\Documents\Programming\workspace\dsafsa\src\tdytd.py",

line 12, in <module>
ImportError: cannot import name 'nested'
Any ideas?
