The kids over at Graffiti Research Lab have taken the game to the next level. There are some incredible videos documenting things like a laser tagging system (shown in the screen snap below) and Throwies (LEDs powered by lithium batteries attached to magnets).
There are also links to "How To" documentation. The How To for "Throwies" is hosted on www.instructables.com where I came across the instructions for turning an Operation game set into a Paris Hilton Operation.
The GRL will be screening the definitive street bombing documentary, STATE YOUR NAME, this Thursday, March 8th, at Eyebeam as part of the Open City Exhibition.
