Lenticular 3D phone/TV

[ocanna@xxxxxxxxxxxxxxxxxx]

Did anybody else see a CNN (I think) blurb about a British concern 
developing a 3D video phone unit?  The concept was to use a lenticular
screen over an interleaved image generated on an LCD display.

An aquaintence suggested a similar idea to me for use on a regular video
display or computer monitor some time ago.  Has there been any other 
developments on this idea? His interest was for use marketing a home 
built airplane kit at trade shows and such.  It would seem a perfect
application for such a display

Several technical challenges suggest themselves.

1. It would seem that registration of the interleaved image against the
	lenticular screen would be critical.
2. On a typical video monitor the phosphor screen is some distance away from 
	the surface of the screen.  Would that cause paralax problems?
3. The layout of the phosphor screen and shadow mask seem to be critical.
	Sony's vertical alignment seems like it would work best but
	on the Sony monitors I've looked at the phosphors seem to be
	a goodly distance from the surface.  That would seem to aggravate
	any problem with paralax

Any paralax and registration problems should be cured by applying the 
phosphors directly to a lenticular screen but that would require purpose
built display tubes.  (Tho if that comes to pass remember you heard it here
first, maybe, and from whom)  If a screen could be applied to a an
existing display unit that would seem to make the likelyhood of such
a creature being marketed.

Of course I may be totaly out of touch on this and a wonderfull product
is alread on the market.  Wish, wish.

What say ye of the list?
