Via The Honi Phenomenon | Futility Closet:
Here’s a familiar illusion known as the Ames room. The woman on the right is not really small, she’s just far away. The room is a trapezoid but is designed to appear square when viewed from this angle. Curiously, a woman who loves and trusts her husband tends to see no change in him even as he walks from corner to corner; apparently she resists a distorted view of him. The same is not true of men.
