There's a kludgy but effective example in the Wavelet Explorer tutorials,
if I recall correctly from awhile back.

My primary reason for replying to this post is to enter a vote (a plea)
for WRI to lower some of the many barriers between its own graphics
world and the much larger graphical world around it. Certainly a
"DeBabelizer" package would be an obvious first step.  Also, I noticed
that WRI was not an exhibitor at Siggraph '97.
