There are very few "cool" videos out there relating to memory. Usually the show, explanation, demonstration, etc. of memory is a re-hashed version of some previous one. For once someone has done it right. In what is one of the coolest videos I've seen in a long time, check out Ben Pridmore's thought process while memorizing a deck of cards....only soundtracked by DJ Shadow and acted it in one continuously shot nightmare-ish stage show: http://vimeo.com/31908447
