Petra, for this kind of image to see in 3D you need glases with red and blue filters..
Polarized 3D glasses (used in cinema theatres) can not be used here...
However, some time ago there were stereo adapters around to be used with classic monitors (Tube type)
They worked like this (the same method is used in cinemas):
There was polarized filter in front of monitor, which can change the polarization every frame (must receive sync signal from computer or TV)... so with polarized 3D glasses each eye receives its own picture (because the left and right filter on glasses are polarized differently)
Of course, to display the stereo images, computer was supposed to alternate display of "left" and "right" image between each frame.
With LCD monitors widely available today, this scheme can not be used (because polarizers are used in those monitors to display individual pixels, so passive polarized glasses are in the way). I think some big manufacturers are working on develpment in this direction... Computer games will be the first to use them, I am sure (if they are not here already, but I am not into games.. so I do not know :-)
