[EDIT : I’m moving this page here, and will update it based on my foundings!] 

I’ve found some pretty interesting material about enthousiasts building up stereoscopic displays at home:
– Here’s a guy who’s building a passive stereo system.
– Here’s a forum which lists a lot of “cheap” projectors to do active stereo.
– Here’s a very recent pdf (aug 06) about the use of LCD monitors and DLP projectors for active stereo. The bottom line: no lcd monitor is good, lot of dlp projectors are good.
– 3D Flight simulator : they have a 2 projectors, active stereo setup, with a tutorial to make a cheap rear-projection screen.
