I stumbled across this video on a Zimbio blog, and was blown away! Imagine using one of those laser-pointers to tag the side of a building 10 stories wide and half a block across?!?
Well, thats not exactly possible (yet!), but these guys at Graffiti Research Lab have combined some neat technology to simulate just that!
Basically, they've outfitted a pc with a camera and software that tracks the light from the laser pointer and superimposes it over what the camera is looking at. Pointed at a building, the camera displays that image on the pc. Someone with a laser-pointer "tags" the building as if the laser-pointer were a paint brush or spray can. The camera then "paints" it onto the building!!
Whomever wrote the software really nailed it: the "paint" from the laser-pointer even drips after its applied!
