I wanted to test my particle system (as described in the message that
I posted in povray.advanced-users) so I decided to create my very
first POV animation.  Since this is my first animation with POV-Ray, I
had to use the mandatory spheres on a checkered plane...  but I have
added some features from my particle system, of course.

I was inspired by the previous postings of bouncing cubes (balls and
springs) so I decided to do something similar.  In this animation,
there are three particle systems: the first one shows three cubes
bouncing on various objects (plane + spheres + cylinders).  When a
shpere hits another metallic object, it generates new particles: some
sparks.  The sparks are the second particle system.  And when a sphere
hits the water fast enough, there is a splash.  This is the third
particle system.

The springs in the cube bouncing close to the camera are very soft.
The other two cubes in the background have stiffer springs and keep
their original shape after bouncing.  Note that I only show the
springs at the outer edges of the cubes, but the simulation also uses
some diagonal springs that are hidden in the scene.

The animation was generated on a Linux laptop (650MHz) using the beta
RC5 of POV 3.5.  It contains 240 frames.  Here are some statistics for
this scene:
Time For Parse/Frame:    0 hours  0 minutes   5.6 seconds (5 seconds)
Time For Parse Total:    0 hours 22 minutes  18.0 seconds (1338 seconds)
Time For Trace/Frame:    0 hours  0 minutes  44.7 seconds (44 seconds)
Time For Trace Total:    2 hours 58 minutes  56.0 seconds (10736 seconds)
          Total Time:    3 hours 21 minutes  14.0 seconds (12074 seconds)

Since this is my first animation, I discovered that the MPEG
compression degrades the quality more than I expected.  Most of the
nice splashes in the background are completely lost.
