OpenGL apparently calls a pixel shader a "fragment shader".

I found a small program that allows you to type in GLSL source code and 
see it applied to a mesh object. Should help me get to know the 
language, but won't help much with rendering a texture of floats. ;-)

The "other" fun thing is that shaders were introduced in OpenGL 2.0, for 
which no language spec is available online. You have to buy the book for 
that. But having a look at the Haskell OpenGL bindings, I think I see 
how it's supposed to work...
