Multi-Touch LED Matrix Display
Twitter Board with LED matrices here
, has Arduino library for text
Place he got led matrices from Sure Electronics
. 125 for a big board >.< and less for a lot of 10, but they aren't 5mm, but might not be able to read light data from it. Want 5mm LED's either way

Best discussion on the internet about this stuff. Series of forum postings.

,REALLY EXPENSIVE!! 64×64 pixel board, have to worry about light levels, but pretty good. Need a computer not an Arduino to do that many analog inputs and updates that quickly
Solid Open Source Projects:
leds plus buttons, really spendy but good sources
…good for graphics but no input
Great example of using two timer counters hooked together for high-resolution audio output
. 440.5 Hz is now possible, but you have to do some math first… Try to understand/copy their well documented source code and simple functions.
Buy red/green displays off of Sparkfun here
$7 each . Maybe get some analog muxes too to read/control everything here
