Lawsuit Waiting to Happen?

Recently on Reddit, this floor design from the UK-based Casa Ceramica tile firm became viral. The illusion, which is situated at the entrance to one of the company’s showrooms in Manchester, prevents visitors from rushing through the corridors. Even more bizarrely, the illusion only appears while you are facing the showroom’s entrance. When viewed from the opposite angle, the “dent” in the floor vanishes. This wave-like surface is actually entirely flat. Some people rightly pointed out that the optical illusion may cause serious injuroes and accidents.
