Download and played with it a bit. Kind of reminded me of Groboto3D but disappointed there is NO export to OBJ option.

Truly wish Darrell Anderson and Braid Art Labs would recommence development on this fine little app.

Tried Curvy3D for some time but just can not get the hang of it. And many of the functions can be done in 3D Coat which is much more user friendly then Curvy3D.
