Moving crowds with an optical illusion sidewalk

"I'm moving that way... shouldn't you?"

Researchers at the University of Electro-Communications in Tokyo are developing a method to subtly influence crowds of pedestrians using the same types of lenses used in novelty postcards.

Lenticular lenses change according to the angle of the viewer. The theory is that if the lenses are on the ground and contain an image that seems to move to the right, the crowd will also move to the right.
