This is one of my favorite videos. After spending a day shooting dance footage with fancy new equipment, we decided to do one last take using an iPhone. I took this footage, ran it through an absolute difference shader to create a negative effect and then created a simple kaleidoscope effect using Max/MSP. The visual trick in this movie is that not all of the transformations are digital – the right-hand side of the frame is an actual mirror image, not a digital mirror image.
