I sure wish my first segmented bowl looked like yours! Are you sure this is your first?
I look forward to seeing what you dome up with next.
My first segmented bowl was made in 2001 and it was a disaster because the only software at the time was a calculator that drew a single ring and without being able to see multiple rings, I didn't have the rings sized correctly and the bowl came apart. That experience was what made me decide to write Woodturner PRO, though, and so I guess I'm glad that it happened.
