Here's another cool opitical illusion and it's one of my favorites. It was originated by Roger Shepard and it's called "Turning the Tables."
Question:
Do you think that the surface of the tables drawn below have different sizes?
What about this:
Well, believe it or not, the size of the adjacent tables in each of the pictures are actually the same. I wasn't totally sure whether or not that the second one is real, but when I rotated one of the tables and moved it close to the other table, it appears that the dimensions are exactly the same. If you want to see the proof, just take a look at an animation of rotating the tables at the links below:
