Ken Jacobs has taken advantage of the fact that there is a greater
perceptual latency with darker images, to produce quasi-3D when one views
any moving picture. Just cover one eye with an ND filter, and the motion of
the picture generates the displacement necessary for the two eyes to
receive impressions from separate perspectives. Ken is surely the master of
this, and he would certainly have more to say about it.
