Order of H'Pak

some months ago, someone sent me a link to this magic ball thing that kinda guesses numbers that you're thinking, and i was like all wowed by it because i couldn't figure out how it did it, i thought it was pretty cool, check it out http://www.exstatica.net/flash/psychic.swf

well tonite i went back to it and was still amazed by it, so i actually ran across a site that tells you how it works. and i was like duh.

Yeah, there's one of those floating around with cards that stumped me. I'll have to try and dig it out - couldn't figure out how it was done.

There was a REALLLLY geeky discussion about that on IMG a couple years ago.
