Ames room

Kai NRG/Geneva built an Ames room. This is an optical illusion where the room is distorted, but your mind assumes that it is actually square, and so objects on one side look much smaller relative to the ceiling, but objects on the other side look much larger. In a true Ames room, the left-hand side of this scene should be much further from the viewer, which leads to a more perfect illusion because both the effect of distance and the trapezoidal shape of the room add to the effect.
