Is there a good tutorial someplace on writing fragment programs? All I can seem to find are the specifications, or Cg and GL Shading Language demos.
what kind of fragment programs, GLSL, ARB_fp, … ?
and if not demos or specifications, what do you want?
I just don’t want to use GLSL or Cg (not sure if that’s even available in OpenGL). Just the pure assembly-like fragment programs. They seem to be more widely accepted than GLSL right now. And demos are fine, but a tutorial would be better.

explore these sites thoroughly, they should keep you chewing for a quite while
btw, GLSL is future of OpenGL, so you might consider getting an early start.
oh, and you can definately use Cg with OpenGL!
