Yep.  I haven't yet found the time to do any in 3D yet, but
I have shot some nice slides of micromounts with a 28mm lens mounted
backwards with a reversing ring.

I've also shot a few slides of my fluorescent minerals.  Kodak has
published a piece in one of their 1960-70s "How-To" books.  I
used my camera's interal meter, metered w/aperature wide-open, with 
camera set to some really high film speed, like ASA 1000, to get a reading,
then re-figured everything down to 64 ASA, and a smaller aperature, tossing 
in some educated guesses for reciprocity failure.  I had something approaching 
2 minute exposures for some of my brighter fluorescing minerals, and they came
out quite nice.  I shot the minerals on black velvet.

I'd like to see that site if you can dig it out.
