HI everyone, I found tonight a nice JS thing:
Meemoo, a visual JS framework that works with HTML5 tech like webcams, user interface response like button, touch gestures or text areas.
I toyed with it for a while and I found it quite easy to use. It's box based with plugs to link between, and presto, you can, for my case, create a neat
Game-Boy Camera-esque dithering + grayscale effect!
I could directly capture the result as a GIF and upload it to imgur :
