There's a roller coaster simulator program named No Limits 
(http://www.nolimitscoaster.de - don't be scared by the .de, the site is 
in English) that uses beziers for creating roller coasters.  I'm 
currently working on a program that will convert a track made by it into 
a POV-Ray scene, complete with animation.

This is a test using a very simple "track".  I haven't actually written 
the program, but I'm creating it in such a way that POV-Ray itself is 
actually generating the coordinates of the spheres using SDL, as well as 
calculating all the physics.  By changing just some array declarations 
at the beginning that define the beziers that define the track, you can 
change the track and POV-Ray renders and animates.

The idea is that all my program will do is read the No Limits track file 
  and convert some binary data into some #declares and then add on a 
standard SDL code to put it all together into a scene.
