Rob,

Here is one that I did at work, though I think this project died.  It might be useful as a matrix sticky.  I have lit more LEDs at once before but this one is a bi-color matrix so it fits more with this topic. 

5x7x2x8=560 LEDs driven by a crumby little 8 bitter.  7 74ABT574s provide the row drive and 10 column transistors with the whole display refreshed 100 times a second.

[edit by Rob: split to its own thread to show off a great project better]
