Want to enjoy movies and gaming in 3D but don't want to spend a fortune on a big-screen 3D TV? You can rig up two projectors with filters and screen material for a (relatively) budget alternative.
User Jahun on the 3D advocacy forum Meant to Be Seen 3- shares his setup where PC game and movie visual data is sent to identical projectors outfitted with polarisation 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 theatre setup.
You'll still need to spring for two projectors, but if you already have one for a home theatre system this could be a good alternative. More information can be found at the source link below.
