How powerful is illusion?
The illusion is powerful enough to overcome other information about the true locations of objects in the room, such as familiar size. For example, although the observer knows that adults are all about the same size, an adult standing in the true near corner appears to be a giant, while another adult standing in the true far appears to be a dwarf. For another example, although the observer knows that an adult cannot change size, they see an adult who walks back and forth between the true far and true near corners appear to grow and shrink.

The true shape of the room, however, is that of an irregular hexahedron: depending on the design of the room, all surfaces can be regular or irregular quadrilaterals so that one corner of the room is farther from an observer than the other.
What happens when you prevent the observer from perceiving the real location of the parts of the room?
