I dunno why, but I have always been obsessed with sculpture that takes a common form or object and stretches it to make it seemingly bend reality.

My favorite example is this sculpture they have on the campus of Carnegie Mellon University. It is a long, tapered pole that goes on into the sky, and it has statues of people walking vertically up it, and depending on the weather and what time of day it is, it has this very convincing effect. Really makes you think that people are walking up into the sky for a second.
