Oh... inspiration... Today I had a bit and did some more tests with the webcam code I already had. So I came up with a bunch of new realtime webcam effects:
The Blender
http://mrdoob.com/lab/webcam/blender/01/This one is well funny. I recommend you to stand in front of the camera, and rotate yourself (your head) by the Y axis. You won't see your head twist like that anywhere else.
Overexposed image
http://mrdoob.com/lab/webcam/overexpo/01/ The perfect effect for an instalation if you wanna organise a trendy digital art exhibition :D
Overexposed image + Abduction
http://mrdoob.com/lab/webcam/overexpo/02/ A modification of the previous effect with an abduction effect applied on top.
Broken Camera
http://mrdoob.com/lab/webcam/broken/01/Weird random line delay. This effect used to happen with some old logitech webcams. Well, more or less ;)
Broken Camera 2 (new)

http://mrdoob.com/lab/webcam/broken/02/Weird random square delay. Just a modification from the previous one. It's fun too.

And here is the bonus for the people that reached the end of this post. The first effect is by far the best one I got today, and you can do really nice distortions effect. Here are some examples:




:DD!
