To promote the Smithsonian's Art of Video Games exhibit in Washington DC and celebrate the 30th anniversary of arcade classic Frogger, the Smithsonian commissioned the making of Fifth Avenue Frogger, a reality-augmented version of the game that pits players against real New York city traffic.
Basically, creator Tyler DeAngelo set up cameras along fifth avenue to record traffic patterns, then wrote a code to translate that information into the original game. Instead of relying on game-style patterns, players will actually have to hop across a busy street. I'm guessing that even veteran Frogger players would have trouble with that,
The creators even brought the cabinet out to fifth avenue and let people take the game for a spin. I bet it's cool to see the real version of the car that just squashed you in the game.
