Graffiti Research Labs - Laser Painter by Rattle at 11:51 pm EST, Feb 21, 2007
This is truly awesome. The folks at Graffiti Research Labs created a rig that facilitates painting with light on the side of a building. It uses a high lumens projector to project the light, a green laser pointer to do the writing, and a security/astrononmy camera to detect where the green laser was pointed. They have made all the code available under the GPL.

I'd been avoided looking at this because electronic writing on buildings has been done before, but their setup is actually fairly cool.

Re-memeing this because this is the project used at Phreaknic this year (Friday night) out on the balcony. Neat stuff!
