Now for something cute!!
The folks at Smart Cars created The Dancing Traffic Light, a concept providing a fun and safe way to keep people from venturing too early into the street. They started by placing a dance room on a square in Lisbon, Portugal and invited random pedestrians to go into the box and dance. Their movements were then displayed on a few traffic lights in real time. This resulted in 81% more people stopping and waiting at those red lights.
