---------------------------------- HPong ---------------------------------- With the release of the Haskell Platform it is now trivial to start making OpenGL programs with Haskell. HPong is a very simple OpenGL game that was made both to experiment with OpenGL and as a starting point for more complex games, since there seem to be fairly few examples of GLFW programs in Haskell. Controls : Up arrow moves your paddle up. Down arrow moves your paddle down. Esc quits the game. HPong is based on GLFW instead of GLUT for the simple reason that GLUT does not provide a working window close callback.
