This hexnuts-disk better demos my original idea. Once we understand how the effect is produce, yes Igor we can Engineer it, producing a much improved artifical version. In this one each nut on the truck wheel is first aligned radially, then each nut in sequence is rotated backwards by 6 degrees. With this setup the flashing facets of the nuts create a VERY obvious reverse-rotation illusion.

Also, whereas my first version had a slow bright blinking which caused distraction, this one looks constant, since it flickers twice as fast as previously. First version: http://www.youtube.com/watch?v=78Mc9k... Also see "blog" at http://amasci.com/news.html
