I have a set of wireless 3D glasses (they are battery powered and controlled via an IR unit that is hooked to a dongle that sits between the video card and the monitor input).
They work with any late model nVidia or Radeon video card and a CRT (LCDs aren't supported).
http://www.edimensional.com/products/edglasses.htmI'm very impressed with them overall. They work perfectly well with all 3D hardware accelerated graphics except those with 3D rendered onto textures embedded in 3D scenes (the textures have -- incorrect -- parallax rendered into them -- needless to say the bundled game makes extensive use of rendered textures :) ) I had an earlier set of 3D glasses and they worked well but had a number of annoying pitfalls:
1) 3D objects were parallaxed but 2D overlays weren't. This caused real issues with UI overlays. The new glasses invert the parallax of 3D objects so that 2D overlays (which don't move) appear to have the largest parallax, and hence float in FRONT of rather than behind the scenery.
2) They only worked with video cards specifically designed for them (I had a bleeding edge GeForce 256 back then -- useless now, as are the glasses).
