DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: 


<A HREF="http://www.novadesign.com">Aladdin 4D</A> has a couple of unusual
features that came in handy here. One is a particle emitter called Fountains. 
Another is heirarchical path-based animation. Instead of the now ubiquitous
key-frame approach, A4d allows you to assign polygons (or fountains, or other
paths) to follow and be otherwise constrained by a path.  Both of these
features were used to make the vortex.

The rest of the drawing is polygon models, with some procedural textures and a
few bitmap textures.
