Yahoo's Bus Stop Derby. Hmm...

Yahoo! has just installed interactive, 72-inch touch screens at 20 bus stops around San Francisco, encouraging people to play against crosstown rivals in live head-to-head social games. The four games range from visual puzzles to trivia competitions. Each neighborhood gets 100 points for a win. Oh, the prize is your very own blockparty with OK GO! Check it out at BusStopDerby.com.
