Hey, this caused quite a lot of response, thanks for the interest.

MegaPov requires Windows, I believe; I'm on a Mac. But it would be nice to
see an example.

I saw it, but let's leave them alone; they're probably making more nanobots.

Thanks!

Very nice! I had a similar idea, but I thought of using a positive light and
then inverting the image afterwards in Photoshop Elements. It didn't work
so well, so I abandoned it. But yours looks great!

(MacMegaPov -- I use it all the time, since my souped-up G3 has problems
with the official Mac compile of POVRay. I "souped" it myself; that's most
likely the problem.)

You can use slope to, and no lights:
camera{location -z*10 look_at 0}
#local TEX = texture{
pigment{slope{<0,0,-10>} //the vector should be your camera position
pigment_map{
[0.25 rgb 1 transmit 0.5]
[0.75 rgb 0 transmit 0.5]
}
}
normal{agate scale 0.2}
finish{ambient 1 diffuse 0} //the ambient controls the brightness
}
sphere{0,1 texture{TEX}}

This is a bit like John Bradshaw SEM texture a few years back.

Just curiosity, have you got an ebook? I'm planning to buy one on January,
because I think it will appear the new one the next year.

Thanks for the MacMegaPov link, Dave, maybe I'll look at it.
Wagner and Rangifer: thanks for the tips, slope maps look good, too.

You should you far less (if any) bluring, electron-microscopes have a very
high depth of field.
(See http://en.wikipedia.org/wiki/Image:Misc_pollen.jpg for example)
