I don't get it -- what's the point? I'm all for reversing for curiosity reasons, but releasing their source isn't cool, IMO. And what's worse is that this stuff really isn't that interesting; these sorts of filters are trivial to come up with on your own. For instance, I whipped up a set of WebGL filters for Boot2Gecko's camera app in a matter of an hour. (If you're curious, you can see a demo at http://demoseen.com/filters/ -- Firefox only, due to laziness.)

Now, a project that compiled a nice list of good filters, that'd be really cool. But this just isn't OK.
