Smart, the folks behind the ubiquitous tiny cars, installed an interactive dancing traffic light in Lisbon, Portugal earlier this summer.

The wait sign at the intersection relays the real-time movements of fellow pedestrians in a nearby dance room to entertain walkers while they wait, discouraging them from crossing the street against the signal.

According the the video, 81% more pedestrians stopped at the dancing red light. Would you want to see something like this in the DC region? Where would be a good spot?
