Late post on Ame's room illusion. Here is a correct explanation of the illusion.
http://en.wikipedia.org/wiki/File:Ames_room.svg
Unfortunately, no 2D image comes with this one, so it does not provide the complete answer.
The "3D" explanatory diagram previously linked by GrahamH is wrong, because it would make the girls of different actual sizes on the image, so that the size effect would not be an illusion.

EDIT: Sorry about that. As you were...
