Its just the first thing that came to my mind when I saw the Griffpatch tutorial. Currently there are two shaders, the edge detector and the "wiggle" shader. To change the image, just change the image in the background and press space. It will take a while but then a white screen will appear and you can press 'a' and the shader will apply. If you have any ideas, remix the project and add your own one. If I see it, I will add it with credit one the bottom of the screen.
Thanks to Griffpatch for the color detection tutorial. The rest is all made by me.
