If you want to experiment with some filters like this in real time, I made a simple page to work with your webcam like this: http://mizzouacm.github.io/javascript-workshop/

You can fill in the filter function to see the effects in real time. You can also get screenshots by clicking the filtered video. It's pretty fun to see what interesting filters you can come up with, and I'm hoping to host an intro to javascript workshop utilizing the demo.

I can't take credit for the idea; I got it from the wonderful Hackers At Berkeley workshop[1]. I am starting a similar club at my university and wanted to do the same kind of workshop. I rewrote the demo because I wanted it to be real time, and I also just wanted the fun of implementing it myself :)

This is cool, but you should really add underscore to the page, as it makes it much easier to deal with large arrays (pixel arrays being the perfect example).
