This is a beautiful AI program which tries to guess what you think in 20 questions. It doesnt really matter on absolutely what you might be thinking but if you answer the questions and give appropriately close answers, this will read minds. Really :)
Check out the program here. It has been around for quite sometime but remembered about it and dug it out from my favorites after reading about it in Steve Maine's blog !
The program has changed a lot from the last time i saw it to this time .. The UI has changed, the AI engine i assume has grown and become more efficient. There used to be a description that this program uses neural networks and fuzzy logic to accomplish this AI task by traversing nodes based on the result for the questions asked ... Very very cool ! Definitely a must try !
I wasn't surprised this time when it guessed an 'Orc' correctly within 18 questions ! Kewl isn't it ?
