Benham discovered in 1895 that spinning black and white discs show subtle colors, and everyone sees different colors. The effect is amazing, and if you watch the disc on the spinning top, as the rpm’s slow, the colors and patterns change.
You can see this effect in action here: http://www.michaelbach.de/ot/col_benham/index.html
I made this for a child for Christmas, from cherry, maple and sapele. For the discs, I found some patterns on the internet and printed them on standard paper.
