Yeah sounds familiar.  I think a mirror with single-axis rotation
would be rather like the technology used in the Private Eye HMD, which
was incorporated into the Nintendo Virtual Boy: they would only need
to project one row of pixels, then rotate the mirror to expand the one
row into a whole frame (and update the row of pixels as it rotates).
But the whole-frame DMD is likely to be the better choice in the long
term, just as the Private Eye gave way to much better HMDs.

I have one of the original ones for the PC at home.  It connects to an
ISA card which emulates CGA in monochrome mode, 640x200.  It vibrates
noticeably in use.  And an all-red monochrome display is not pleasant
to look at for long.  I ran across one in 2000 and picked it up
because I remembered the article announcing it in Radio-Electronics or
wherever it was, when I was much younger.  :-)


Another way which has shown a lot of promise is a combination of
lasers and holographic optics, which I don't understand very well.
(How to make the laser scan the frame, preferably without moving
parts, or only microscopic/nanotech ones?)
