	But what great effects!  I have chase lights in all different
directions, text that can scroll everywhich way, random blinking...
Heck, I even have subliminal messages built in.
Now if only I could find a stadium that needed a fancy scoreboard :-)
	But, seriously it was more to teach me embedded
programming and design of 68k based hardware (we use 68k's in most of the
equipment we build here at work, so the parts are cheap, and we have
emulators, compilers, and all the goodies one needs for these things).
	It was a fun project, despite being relatively useless.
