I had some LED's laying around and a microcontroller, so I built this with my rooommate in an hour or so.
With multiplexing, we can make huge arrays that are completely controllable with images, scrolling text, etc. Just uses some C programming and a bit of creativity.
We started with simple loops, random function, and variable delay for some neat but simple effects.
