I had a pair of eDimensional 3D LCD shutter glasses back about a year ago. I ended up returning them, but wouldn't dismiss this technology at all, especially if any of these products are really good at what they do. The particular glasses I had were recommended for use with CRT monitors and nVidia cards/drivers (not sure nVidia supports them anymore). I had an LCD monitor and an ATI card so I had to use their "universal" drivers. Basically, this was enough to show off the enormous potentail of the glasses, but every game I tried ended up having some serious quirk that led to me ultimately getting rid of them. On the other hand, playing games like Oblivion, Lock-On, and a few others introduced a 3D immersion that to this day I really, really miss having (if only the games were actually playable!).
