There's no gravity at all in that scene, the particles are more or less only
moved by the turbulenced field. More like dust-particles in a water-basin.

Problem with that was rendering times. Using blob to "connect"/merge the
different particles to each other would increase rendering times
drastically, and merging particles to the surface of objects would be quiet
complicated to achieve more realism than just sinking the spheres half-way
into the surface...
That aside, I also wanted to show that particles can have a radius and will
properly interact with the environment.
