i know how both these tricks work, but you might not..at first.. http://www.cyberglass.co.uk/assets/Flash/psychic.swf http://www.flashhog.com/swami/
The swami one replaces ALL the cards. Any one you pick will disappear.Write down the cards first and see.
yeah, now the site says: "This site is being moved to another server and should be available again within 48 hours."
I knew the card one from a thread before on ET. The other one had me stumped but I figured it out. It was a bit freaky until I did, though.
what was your conclusion? this is the answer: when you do the math it tells you to do, you will always end up with a number that is a multiple of 9. all the numbers that are a multiple of 9 have the same icon. here's what's really tricky though... every time you do it, all the icons change. however, the numbers that are multiples of 9 will still match. i think it's a cool trick.
I suggest you delete this so that other people who come across this are left clueless for a few minutes like I was. :-D
