DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: 


 All frames were rendered at 320x240 with anti-aliasing. The full source is
 in the zip file. The main elements are as follows:

 - Scene

   The salt-flats are a plane with a random texture. As things speed-up,
   the texture is scaled larger in the direction of motion to simulate
   motion blur.

   The track markings on the flats are polygons and text objects placed
   just above the surface.

   The surrounding hills are height fields which have been rendered into
   a separate file.

 - Car

   The body is made from cylinder blobs with scaled spheres for the nose cone
   and the canopy. The 'wings' and tail plane are cones which are scaled and
   then cropped.

   The rocket flame is media with a random density pattern which is translated
   to give a flickering effect. The image distortion when it first starts up
   is done by using the ripples normal pattern in the camera normal.

   The exhaust trail is a line of spheres with a random transparent pattern,
   with the sphere sizes set by a random walk (ie. each size is the previous
   size plus a small random change).
  
   The tyres are scaled spheres which are transparent and filled with dense
   media to give a solid look. This allows the density to be reduced to give
   a softer 'motion blur' look to the tyres at speed.

 - Cockpit Forwards view

   The cockpit is made from standard primitives. The arms and hands are made
   using a limb macro which creates a line of randomly displaced spheres with
   random textures which almost looks like cloth if you stand far enough back.

 - Cockpit Backwards View

   The body and arms are made using the limb macro described above. The helmet
   is two cropped spheres with a cut out and an image map for the face.
