I have always been kind of fond of scenes/advanced/piece3/piece3.pov
It's not only a classic from the early past of POV-Ray, but a comment
in it is really telling:

// Rendering time using a 25Mhz 386 w/Cyrix fpu is approximately 60 hours.

  This is a really excellent testament on how much computers have advanced
since those times. Current top-line PCs can render this scene at a high
resolution in question of seconds.
  In fact, now it can be raytraced almost in real-time. I suppose Truman's
jaw would have dropped if he had seen that after he waited 60 hours for
the render to finish.

  For a nice animation of this scene, open scenes/advanced/piece3/piece3.pov
and substitute the camera block with this:

#declare Clock=0;
#while(Clock<1)
camera {
   location  <  7.0,     50.0+10*sin(4*pi*Clock), -30.0 >*(1+.5*sin(2*pi*Clock)) /* Up
high and in close.         */
   direction <  0.0,      0.0,   2.0 > /* Though this doesn't highlight */
   up        <  0.0,      1.0,   0.0 > /* the height of the piece, it   */
   right     <  4/3,      0.0,   0.0 > /* gives the effect i'm looking  */
   look_at   <  0.0,     15.0,   0.0 > /* for.  Feel free to change.    */
   rotate y*Clock*360
}
#declare Clock=Clock+.01;
#end

and then render with eg. +w320 +h240 +bm2 +rtr +kla
