There is a number of really cool Flash webcam effects emerging from different developers across the globe. I'm fascinated by this technology as it opens a greater potential for games and enhanced website interfaces.
This is a very short list of some of the coolest Flash webcam effects.
3D Glasses Enhanced Face Tracking
This very cool flash effect tracks your face using the web cam, when you move your face you move the small room around. The effect is also enhanced if you are wearing 3D glasses.
Webcam Baseball Game
This webcam game brings your Baseball collector cards to life with mini games.
3D Animated Paper Tracking Effect
This demo is a paper tracking and sound enhanced Flash effect. Move a printed document in front of the webcam and a 3D animation of Wind Power will appear in front of the document. Blowing will also increase the spinning speed of the fans.
