I came accross this website which I thought was very well done:

http://y.20q.net:8095/btest the computer can guess what you are thinking of after 20questions... it gets it right or pretty close most of the time...

there's also elbot the talking robot which you can chat to:
www.elbot.com

pretty good choice (20 questions with 6 variables) - nice and neat.

lol just tried something new - still inside 20 - but a lot more variables lol.

still a tidy method though.

was close to wot i thought..

That's really neat, Rezza. I remember AI The Movie having a really nice AI chatbot.

Nice...

ugh. stupid school. well i can't get to the 20 questions because our IT teacher says that it's a game, but i have seen something like it before. they guess fairly close to what i'm thinking. then again my thought patterns are kinda twisted.

I'm up to abot 67 questions and it still hasn't got what I thought of.... maybe I should think of something more reasonable...

I was thinking of egg and it guessed pouridge. I'm probably not giving the right answers.

I was thinking of a bear and it guessed correctly. I love this AI system! NEAT-O.

yeah it's pretty good, I thought demon and got it. Elbot is pretty cool too, any comments on him?

I didn't test Elbot out.

I thought bear and it gave raccoon.....

It's right maybe 90% of the time for me. Are you sure you are giving legitimate answers?

I think so. I'll try it again here soon.

LOOK AT www.elbot.com PEOPLE... ELBOT.COM!

NICE

lol this machine sucked..i beat it every time...couldnt guess worth **** lol
