Can anyone remember the name of a high-res camera-back
that used a tiny movement of the sensor to double
up the resolution?

I've googled and failed :-(

Sounds like "sub-pixel rendering."

Further searching revealed the "imacon"

Just move the camera around at random, and take lots of pictures. After some
multi-pixel alignments, should be many shots with remaining sub-pixel shifts
that could be used to boost the resolution. You just have to determine what
the alignments are, which should not be hard to do in Fourier space.
