Jacob,
I have been working in the area of whole-body vibration for a number of
years and the only technique for visualization that I have seen
demonstrated was by David Wilder at Iowa. His homepage is:

I hope that helps.
Neil.

I have not seen the picture you describe, but your description is
reminiscent of a technique called contour photography. The photos taken in
contour photography appear to overlay a contour map upon surface of the
body. I don't know if this would record vibration. If this seems
promising, I can find a little more information for you.

Jacob,
I remember watching a video series entitled Science and Music in which a
technique similar to what you describe was used to show how vibrations in an
instrument (violin, guitar, etc..) can travel through the body. Check the
following URL for specific info -- be warned, though, that this was a 5 part
series, and the segment I refer to occupies about 1 minute out of 5 hours of
tape...
