Good morning, this floor is flat. I know it looks like something off the cover of a Dr. Seuss book, but I am the Thomas Friedman of floors, and I am here to tell you it is flat, and was probably designed by a bunch of sadistic people who would like nothing more than to watch you trip and fall on your face. Actually, it’s the entryway to a tile company’s showroom in Manchester, England. Which, frankly, is a pretty good way to sell tile. But also, the “falling on your face” thing. (On the upside, the illusion only works from one direction. The floor looks normal walking out of the building.)
No running in the halls.
