At first glance it seems like just another fun art project, but this dancing traffic light can actually vastly improve safety wherever it's installed. Because people waiting for a 'don't walk' sign to change to 'walk' are far more likely to stick it out when they're distracted and entertained, rather than just try and walk through a red light when they tire of waiting.
