This is code for running various LED displays.

It has grown to also be where I dump code for doing low-level I/O
with various development boards.

Originally intended to function as CPU usage meters, the code
also includes demos for things such as clocks, space battles, 
music visualization, etc.

              either over a parallel port or USB
