There is such a device!

The lens board 'jiggles' at 3 to 6 Hz, tracing a circular path.  There is a
definable distance upon which the motion centers, an adjustable "convergence
point".

The results can be displayed in (film) projection or on video screen.  It
requires no glasses to view it.

Christopher Mayhew of "Vision III" (Herndon, VA) uses this system to create
"SCA" or "Single Camera Autostereoscopic" images.
