Papervision - Augmented Reality (extended) from dpinteractive on Vimeo. This is AWESOME! I have this running on my desk at work :) http://interactive.digitalpictures.com.au/?p=392 The software is flash bassed (unlike others) so there's no install necessary it runs in your browser, just print out the paper symbol and point your web cam at it! (trim the printout down so theres about a centimetre of white around it) http://interactive.digitalpictures.com.au/?p=392
