The GLUT package contains all examples from the Red Book, see:

   http://darcs.haskell.org/packages/GLUT/examples/RedBook/

The coding style is probably not the best one can imagine, but the intention 
is to give a very close 1:1 mapping of these well-known examples in Haskell. 
If you have read the Red Book (what everybody trying to do some OpenGL 
programming should have done IMHO), you should have no trouble understanding 
the Haskell examples.

As already mentioned in another post, loading image data is by design out of 
the scope of OpenGL, but the examples contain a loader for a trivial raw RGB 
format:

   http://darcs.haskell.org/packages/GLUT/examples/RedBook/ReadImage.hs

For further questions, hopengl at haskell.org is probably a better mailing list.

Cheers,
