WOW! Very very nice.  The first time I got a strange variation with 
three (or more) objects, including a skinny one in front and some chubby 
ones behind.  Then I wiggled my eyes a bit to far and lost it.

When I got it back I only had one perfectly formed object, and the 3D 
lock was among the best I've ever experienced.  I had no trouble with 
the illusion that I could reach into my monitor and pick it up.  Love it!

If you have time and/or inclination I would really like to see a short 
tutorial (with source) on how this was accomplished so I could do it 
with object(s) of my own design.

Thanks for posting!

ps:  A long time ago somebody told me that the best way to see one of 
these (for beginners) was to display it on a shiny surface and focus on 
your reflection.  Just a trick to double your focal distance I guess. 
Today I managed to look at something on the wall behind my monitor and 
that worked.
