This is a pretty clever idea. Take the classic game Frogger and update it with a feature that never seems to work right on my GPS, Real Time Traffic. That is exactly what the people at 5th Avenue Frogger have done. In their version of Frogger is similar to the original, except the traffic you dodge in 5th Ave Frogger is actually traveling down 5th Ave in New York City as you play. You can see what I mean in this swell video the put together.
