the version I use, i got from 'Tricks to Freak out your Friends' by Pete Firman, my method isnt 'thingy free' but iv done it with a short sleeve tee-shirt to my work colleagues in the pub, after work, i had one of our 1st aider's(who is a St Johns Medic) tap my pulse out!

was great! i used the heavy to rasping breathing, then silent breathing and my head drooping down 'trance like state!' i think its a really good effect, and is easily set up! (the method I use, anyway!) oh, and why have we dug up a really old post? lol
