Darth Vader can read your mind

Check this out - http://www.sithsense.com/ - its a quiz of sorts, where you think of something, and then Darth Vader asks you twenty questions and tells you what it is.

Its surprisingly intuitive - I picked a very obscure animal, an ape called a Bonobo, the quiz asked me some very vague questions, and then correctly guessed at what I had been thinking of.
