Mine too. Let us not forget single lens stereo!

And now for something completely different...
A couple of guys who used to work at Tektronix, received a patent last 
year for their "Stereoscopic hardcopy methods". The abstract for Dennis 
Hall and Philip Johnson's invention reads: 
"A full color stereoscopic hard copy is printed using a first group of 
color inks that reflect one handedness of circularly polarized light and 
a second group of color inks that reflect the opposite handedness of 
circularly polarized light. One image of a stereo pair is printed using 
the first group of inks and the other of the stereo pair is printed 
using the second group of inks."
I've heard that others have been using  Cholesteric LC-Silicones for 
stereo printing.
Anyone here with experience with this stuff? Can these inks be used with 
film dyes? Will I need to buy an additional cartridge head for my 
printer? Inquiring minds want to know.
