This somehow spooky design was made with StippleGen. I did nur use a V-bit, but a very fine down-cutting bit. I did stain and oil the surface for a better contrast before carving it.
It takes considerably more effort to create a real 3d transformation. Besides the higher usage of material this slot-in geometry has to be glued. The rigidity is pretty impressive – even on a 6.5 mm baltic birch plywood: no problem on carrying a large pot.
