This simple design is based on the Archimedes Spiral and show how far you can bend wood ... even if you deal with plywood.
My build was done on a desktop cnc-machine by Stepcraft from 6 mm birch plywood using a spiral-toothed 1.2 mm flute. The top panel had a beautiful dark inclusion, which would be traded as fault in many cases.

I used Illustrator and a script written by Sato Hiroyuki to create an approach of the Archimedes Spiral.
