[PD] LED on the Cheap

[Alvin Google]

I am writing a proposal to use Pure-Data to control LED panels that 
would light part of a rock quarry. The panels should both illuminate and 
show pixelated imagery (the resolution dependent on the quality of 
LEDs). I would looking for the cheapest and easiest solution. It has to 
be visible at some distance so the panel size would have to be at least 
2 x 3 meters. This sort of application is completed new to me and any 
and all advise would be super helpful..

Thanks
