Just about all the 3D stuff I have seen was done using crossed polaroids like that - although I did see one old system on the Isle of Wight (at a 3d Exhibition in Bembridge) where they used glasses with shutters that alternately opened and closed in synch with the screen.

The only time I've actualty seen red/blue 3D that I can remember was an old video game on the BBC Computer.
