Mainly a small machine that moves your camera in millimeter increments to a subject.
Mainly macro photography.
Subject 2 inches away, the machine moves your camera ever so slightly towards the subject for a set amount of shots, ie., 20.
Then a stacking program puts them all together so your subject (say a fly) is focused over many points and the dof is fantastic.

From Wikipedia:
"Focus stacking (or hyperfocus) is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images. Focus stacking can be used in any situation where individual images have a very shallow depth of field; macro photography and optical microscopy are two typical examples."

Ya, I meant to say it that way.

You need a tripod and a focusing rail. You focus at the front of your subject and then use the rail to move your camera. You have to take 7 or so shoots. The you down load to your stacking program. I use Helicon Focus. And it will combined all your shots into one. That gives you sharp pictures with no DOF problems.

Hi could any member pleas tell me what focus stacking is ??
Picture one was taken with a D300 & 105 macro lens tripod mounted on the focusing rail (#2). The plane of focus is incrementally moved and the resulting images are combined using a program such as Helicon Focus. The blossom is the size of my index finger nail

owners there is a firmware 'hack' called Magic Lantern

Mainly for the video guys, but lots of nice additions for stills shots.
It has a 'section' (if that is what you would call it) for focus stacking
I have Magic Lantern for a while now and find the focusing assistance a great help.
Sorry folks, but it is only for Canon cameras so far.
