I'd like to write a Haskell program that executes an IO action every
50 milliseconds.
It would be most helpful if someone could point me in the right direction.

Hello Matthew,
Check out forkIO and threadDelay.
http://www.haskell.org/ghc/docs/6.12.2/html/libraries/base-4.2.0.1/Control-Concurrent.html
Basically, you can fork a thread and then have it do something, delay 50 ms,
and then invoke itself again.
Edward
