Was this the technique where alternate frames are for alternate
eyes?  If so, it has lots of advantages, in addition to those
you mention, handicapped people with only one eye can perceive
the 3D effect!  Apparently the brain compensates somehow for
the time-division multiplexing involved.  The one real disadvantage
is that you only get effectively 15 HZ refresh instead of 30,
so there is a greater possibility of flicker.
