Hi,
Below is what I've thought would make a good, but inexpensive, 3D system (not had the opportunity to try all the parts out though): Edimensional glasses (not compatible with the old Stereographics goggles and emitters - dunno the exact wavelengths, but from visual appearance of the LEDs they are different) 35 ft emitter: http://www.3dflightsim.com/product/product_index.htm (yes, you need high powered emitters for long range) GFX: I've heard of people making cheap gaming cards work for 3D (note: if you're using Linux, in think you need to make sure that stereo works for OpenGL, not Direct3D). As has been mentioned before, some of the Nvidia Quadro FX cards are great and easy to setup in Linux, and not too expensive. Projector: DepthQ is inexpensive as far as "3D" projectors go, but there are forums which mention run of the mill projectors working perfectly well in 3D. I'm sure there are people who have more detailed info on this subject.
