[Haskell-beginners] Haskell and OpenGL

[Tyler Hayes]

For anyone comfortable with OpenGl in Haskell,
what is the equivalent for glutTimerFunc?
Is it addTimerCallback?  If so, how does it work--I've tried it and I
can't seem to get it to work...

It's really odd that there are straightforward implementations of
callbacks for display, window resize, keyboard/mouse, etc., but not for
something as common as a timer callback.

Thanks,
Tyler
