Congrats, on the Creativity Award for that Light Array.

How do you drive all those LEDs with only 8 LED outputs?

I did something similar in 2004 and I used the LED drivers as select lines to a multiplexer. With 5 LED drivers for select lines you could select the 25 LEDs and still have 3 left for the other LEDs.
