In Googling for an explanation as to why high speed fan blades appear to occasionally spin in the reverse direction, I managed to find these. Trippy. I've always been amazed by artists. I especially like the sidewalk 3D stuff. I seen that here once and WHOA...felt like I was falling in the sewers it was awesome!!!

p.s-As for my own search I assume it's because the tip of the prop is moving faster than the center? Anyone know of reference which explains this phenomena?
