A newly emerging software program that allows the user to actually draw 3D wireframe models in real time. It's called Rhonda.
This is James Patterson creating his trademark fascinating figure drawings in the round.
The link for the software is down now, no doubt crushed by the mass of traffic it's drawn. Once it's up again, check it out at rhondaforever.
I got this video from drawn.ca where you'll find a little more information about the developer and even more information in the comments section.
