Build a Passive 3-D Projection System [Home Theater]

If you want to enjoy movies and gaming in 3-D and don't want to spend a fortune on a big-screen 3-D HDTV you can rig up two projectors with proper filters and screen material to rig up a budget 3-D home theater and gaming system, especially if you already have one projector.

User Jahun on the 3-D advocacy forum Meant to Be Seen 3-D shares his setup where PC game and movie visual data is sent to identical projectors outfitted with polarization filters and projecting onto a screen made from silver screen material. He also added ducting to move the heat from the projector exhaust to the HVAC air refresher system to keep the heat down in his attic theater setup.

Personally, I'm not that into 3-D but if it does the trick for you this seems like a very interesting setup to try out. More information can be found at the source link below.
