A rather funky explanation of how general relativity works

Pretty damn cool, actually.

I remember drawing lines on an orange to try to explain to someone how there were more than three dimensions in the real world and how Euclidean geometry just didn't work. I also tried to explain things using a lemon suspended in a fish tank: shake the tank but all the pips stay in one place inside the lemon, despite the movement of the lemon.

I wonder if there are any more fruit-based visual aids to relativity?
