Make:

so, these various levels of LED intensity made me immediately think of rasterbator ( http://homokaasu.org/rasterbator/ ) which is a script that converts an image into halftone dots (think like you're zooming in on something printed on a dot matrix printer).

to make an array of these LCDs that would display rasterbated images would be pretty cool!

I saw some work in a exhibit by Eric McNeill last summer who was doing something similar, only his were were much larger and on open frames with the LEDs soldered directly on to the bare wires, forming a grid. The LED's were pointed towards the wall to be the "display". He has some videos / photos on his site:

(PS - I don't think there's much DIY about letting someone do all that fun work for you!)

this reminds of the "arcade"-installation in paris a few years ago, where the windows of the national library were used as a simple screen:

who wants to build his own led-panel: the arcade mini website is a good starting point:
