A free moving Torus with spiraled profile, rotating around and moving forward in a smoothed-particle hydrodynamics (SPH) particle bath, half-view. The driving force is the spiraled profile that spins round the knotted string at a constant speed. This simulation is made by computer artist / scientist José 'El Gato' JAHC http://www.youtube.com/user/jahkr (ref. 414-torus-only-free-nf-af-1)
