Jim, that is cool. Technology has advanced very far, and I see no end to the advancements. I bet the structures look fabulous, to see all of the intricate joinery.
Splinter, I hear you on the robust joinery, something with a lot of pieces that comes together are a unit. The bench that I have in the shop is along the same lines, used 2x6's left over from the shop build and ripped them in half, cutting dados and used tenons on the legs. Should have used a draw bore pin though. I'll be building another bench one day.
