had one of these down @ the so-cal camp. Bowl made from 3 laminated scraps of bamboo plywood. 18" dia., 5 paths, 1/2 straight bit, 1/8 downspiral, and 1.5" core box. about an hour and a half cut time. 2 sided machining with cut3D and Vcarve. The cool thing is that all of the lines and circles are a direct result of the way the material is made in conjunction with the curve of the cut.
anyway, I brought one of them up to give the supplier (www.calibamboo.com I have had nothing but great service and a good relationship with them as a customer [otherwise no affiliation])
they shot me back some professional photos they had taken.
thought I'd share.

Do not follow where the path may lead. Go instead where there is no path and leave a trail.
