They aren’t the best res (320 x 240 per eye) but are great to experiment with and you can see if you want to buy something better down the road. They are like the ones in the spy car kit but are color and include two displays. If you have any interest in them I will be getting rid of them for cheap pretty soon. Just comment below if you have an interest in fiddling with these type of things. Here is the product’s page… http://www.kopin.com/bdm-230k/

I still have 3 different LCD glasses;

* iTheater – 320×240, lightweight bright, long battery life, not very good optics (dark diagonal corners syndrome), the +v line in the wire broke and haven’t bothered to try and repair it yet

* i-visor DH-4400VPD – old, 800×600 resolution, can do full 3D by interlacing or through dual VGA or composite video inputs, ok optics but the LCD screens are B/W and colour is achieved through a flashing RGB LED behind the screens meaning they flicker, not very comfortable to wear

* Sony Glasstron PLM-S700E – despite being many years old these LCD glasses are simply superb, Sony went to town when they created these, comfortable to wear, excellent optics onto a 832×624 resolution (native unscaled 800×600 PC input or 1024×768 that scales down to 832×624), the only drawback I found with them is the lead between glasses+controller is too short and the controller is noisy because of the fan inside (it consumes about as much power as a PS2). They’re amazing for playing driving games on.

I have also owned some Olympus FMD-200 glasses and whilst they’re old and low resolution and the image isn’t 100% scaled properly, they’re very comfortable and the optics are superb (one day I’ll get another pair), as well as some Rimax Virtual Vision 4.0 glasses that despite 640×480 resolution they were uncomfortable to wear and had atrocious optics, uneven brightness resulting in the diagonal corners of the image being dark.
