I did...I will probably use the threads package to do the mouse,
keyboard
etc I/O type of stuff. Unfortunately, it only interrupts at 50Hz (is
this
right?) so its not fast enough for real-time sound mixing using the
intterupts... Unless anybody has any other ideas? ;)

Say, does anybody know anything about texture mapping? My code is giving
me a major head ache... :)
