This is neat. It’s a video showing off skeletons of the top 100 popular Spore Creatures using Flash and the Spore API. The creator of the app made two versions: a normal view of the skeleton and an “augmented reality” view…in which you can use a printed marker to see the skeletons with you in your own webcam! Very cleverly done.
You can check it out here. Don’t forget to watch the video of the demonstration!
