Nice!

Have you seen the one where they project graffitti onto a building? They draw it with a laser pointer being tracked by a camera. I think that was in Sweden though.

Scandinavians must like their hacks big.

Didn't see that one. The building where they played the tetris is just 300ft from our office and 1 mile from our home. :)

Yeah, they have LED lights in each window. They are controlled through PC and then again in the game and finally the game is controller through a cell phone.

How does the laser drawing end up being so smooth and not twitchy? If you shine a laser at something, and photograph the spot with a long exposure, the laser will look twitchy. If you turn the laser off, say, to start a new word or letter, it is very difficult to determine where it will be pointing when you turn it on again for the next letter. Especially at those distances. At a distance of 1 mile, every degree of error is 6 feet (I think).
Either I am not understanding what they are doing, or I need to switch to decaf.

They are doing a bunch of smoothing in their software.
