Do you get frustrated when a big group of people strolls down a narrow hallway spread out from wall to wall? If you're in a hurry, it can be almost impossible to get past them. This weird looking flooring is designed to end that problem, by subconsciously nudging people over so they walk on the right.
The floor uses lenticular lenses like those cheezy postcards that change depending on your viewing angle, only in this case the tile sections shift from dark to light in a pattern that moves over towards the right. This tricks your brain into following the direction the pattern appears to be moving, over towards the right wall.
If this actually works, I would be in favor of paving all New York City sidewalks with this stuff.
