There are some nice examples (binaries) of [Haskell + HOpenGL] programs at: www.cin.ufpe.br/~haskell/hopengl/examples.html I think they may be of interest to the community because they confirm that it's really possible to use Haskell in the development of complex, fast and robust graphic applications and games that involve animation and other interesting issues (texturing, lighting, checking and analyzing multiple user inputs, etc.) -- Andre
