Hallway Optical Illusion
How would you like to walk down this hallway? It is made entirely out of tiles and while it looks like it is sinking on the right side, it is a perfectly flat surface. This bizarre hallway can be found at the Casa Ceramica (a tile company, of course) showroom in Manchester, England. It took a total of 400 porcelain tiles to complete this warped checkerboard design that doubles as the showroom entrance.
