I found my solution at > <http://www.photo3-d.com> That was the other Brian, but I looked at the web page you cite, and I can't see any hint of how you found your "solution" on it; in fact the very last text on the page is: "Like a 3-D movie, you just wear the glasses to see the 3-D effects." (Incidentally, it's interesting to note the way they - fairly successfully - manage to make a 2-D impression of looking at a 3-D print. Actually looks more realistic than the "real" 3-D print; shouldn't it say "simulated image"?!) I've never seen a 3-D movie; I get the impression they were very popular in the US at one stage, but I grew up somewhere else, actually close to where the man who discovered stereo vision lived. His name was Charles Wheatstone, and it seems to have been an amazingly late date (early 1800s) for the connection between seeing 3-D and having two eyes to be realised.
