this is a revisit of this project:
vimeo.com/833406

while back then the framerate was 10-20 fps at 640x480 pixels(the video back then was actually kind of prerendered), this new version still runs at 60 fps at a resolution of 1024x768(DAMN THAT IS FAST).

The huge speed imrpovement is because I portet the whole thing to GLSL using texture lookups which makes things alot faster. The funny thing is that there is still alot to improve in terms of my FBO handling. Anyways it's fast allready!

Also the ripples could maybe need some extra smoothing.
