This traffic light convinced pedestrians to wait with dancing

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?
