I have been playing around with image based particles. That is, particles based on the color values of a source image. Along the way I came across something interesting. I mapped the speed of the particles to the white value of another image. Which causes the pixels to move in a cool 3D-like way. The part I dig the most is that there is no 3D code at all. I think I will be doing more with this in the future, as it has a lot of potential. I have posted a demo as well as the source of this below.
