 International actually released a few 3-D videos with one
 widescreen left image on the top, and the right widescreen
 image on the bottom. The two 2.35:1 widescreen images fit
 nicely in the TV's 1.37:1 frame. How was the 3-D effect?
 I can't say for sure, because I don't have the special prism
 glasses to properly merge the top and bottom 3-D images. >>

A friend of mine has a 3-D video system which uses the same over/under video
you mention here.  His system does not use the prism glasses (I've got a few
pair of these around here somewhere) but instead uses a polarizer & mirror
system that attached to the front of the direct view (not projection) tv.   I
don't remember it working extremely well since you had to be in just the right
position for the mirrors to be properly aligned. 

 Has anyone seen other rare 3-D home video systems?  How about the LCD
predecessor which had motorised glasses? I think I saw this in an old (50s?)
Popular Science magazine but I don't know if it was ever produced.  It looked
like a toilet paper roll spinning in front of your eyes with 2 eye holes in
it. As the tube turned you could see through the holes allowing the
alternating view to be seen by the correct eye. Flickering pix?  

How about the Vectrex video game system (early 80s?) with the optional
motorised spinning color wheel built right into the 3D glasses?  Yes the
glasses would vibrate as the color wheel spins pretty darn fast.  

Didn't someone take 2 televisions and some fiber optics and manage to create
3-D television by carefully inter-mixing the fibers from the front of each set
to create a picture screen display. I don't recall if this was polorized or
lenticular but it had to be a lot of work to build the thing.
