Although it's not clear what was causing people to run into Casa Ceramica tile showroom in Manchester, UK, what we do know is that the staff there were fed up with it, so in order to slow people down they came up with a genius solution. One that involves the clever use of an optical illusion.
Is there now a hole in the floor? there sure isn't, but to any new potential customers now entering the showroom it looks as if there is and according to it's owner Duncan Cook, the floor has has a profound effect on the speed in which people enter the showroom.
The effect also showcases what can be done with tiles and is only visible on the way out meaning those leaving won't feel the same vertigo inducing effects.
