DVD Fridges
These fridges
look sort of fun (although ultimately useless). They accept flash cards and play more formats than most DVD players. I think it would be nice to use the 96KHz dolby digital sound to recreate the sound of a real fridge.
The other thing I found from this manufacturor (who are going to be making the PS3s very soon) are these monitor glasses
. The models have 640×480 or the reather strange 800×225 resolutions. The other question is how quickly do your eyes strain from looking at something so close.
