I was playing with chrome/mercury blobs :
http://www.blastwave.org/dclarke/povray/output/chrome.avi
http://www.blastwave.org/dclarke/povray/output/tet.avi
I was trying to figure out how to make surface ripples on the blobs that
would emulate ripples on a still pond or lake but wrapped onto a sphere.
I figure that the only way to do this would be to tessalate the sphere
manually and then add a sinusoidal interferance effect to the surface that
would be a standing wave pattern in 3D. While it may be possible to add a
bump map effect in a still frame I wonder about an animation. My hope is
to create a reasonable animation of a sphere that has droplets falling away
from it radially first and then downwards due to spinning.
Any thoughts ?

Neither of your movies play on my Mac...they probably use a codec that I
don't have.

Tessellating the object could work. You could then do an actual
simulation of ripples going across the surface.
If the ripples aren't very deep and don't need to be very accurate, just
a ripple effect is good enough, then some kind of procedural normal
pattern would work better. If they are deep but don't need to be very
accurate, an isosurface with the same procedural pattern would work.

the odd thing is that I produced them both with QuickTime. The codec is
Intel Indeo .

How ancient was the version of QuickTime you used? The last time Apple
included this codec was in QuickTime 4, about four years ago. Even
Microsoft stopped including the Intel Indeo codec in Windows XP SP1...

You can if you have an old version of QuickTiem installed (3 or 4 should
do), or you may be able to run it on Mac OS 9 (not Classic) with a current
QuickTime if you download the old Mac OS 8 codec from
<http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/En
glish-North_American/Macintosh/System/QuickTime/Indeo_Video_5.smi.bin> and
install it.

Interesting. Did you have 4.0 on that system before? Otherwise, I guess
QuickTime is able to use Windows codecs already on your system (Ididn't know
that)...

let me think .. uh .. no .. that is a fresh license. It is possible that the
codecs were picked up from the system. Microsoft Internet Explorer will
launch Windows Media Player and they work.
