XBALLS.MPG is an Xing-compatible mpeg (160x120 x 36 frames).

The scene is of 4 chrome and 4 mirrored balls rotating around a larger
glass sphere. After generating 36 frames (2.5' rotation each) I passed the 
resulting TGA's thru CMPEG which generated my animation.

NOTE: it may appear to run very slow on some machines... this is because of 
the small increment of rotation.  The advantage is that on a fast machine, 
its very smooth in its motion!

Here is the Pov-Ray2.0 file I used for each frame of motion:
