Like being entertained while you are waiting?

It's a dancing walk wait signal.

You'll love this short video.

The MOVEMENT of the figure is causing the brain of the pedestrians to do a hard reset as it continues to do RANDOM dancing motions. Your brain does everything it can to STOP YOU IN YOUR TRACKS until such time as you figure out what's going on.

In this case, it happens to be entertaining, even for adults. And it stops people from jay walking.
