Spinning top designed for Benham's discs

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.

Looks great and I think it’ll look greater when playing with it; I think I want one.

The colors are very subtle, so you have to look close.

At that link the default speed is 0.9 rps, but I don’t see the colors clearly until you speed it up to at least 3.5 rps, and then they are shades of brown.
