John Nilsson is the man behind the jDome, an invention that will give gamers a massive 180-degree field of vision instead of the usual 15 to 20 degrees they get from their monitors. All you do is put the jDome in front of a projector, mirror the image in the projector, change the Field of View and you're good to go. Nilsson's already patented his idea, and he's looking for donations to get the jDome into production—he reckons it will cost between $125 and $200. [jDome]
Meh, unless it actually improves your vision of the game, then it's useless. He's just stretching the default view out to accomodate 180 degrees of vision rather than adding extra screen space to the viewable area and stretching that out. This system would actually give you a disadvantage because you'd be seeing less of the game in focus.
It's a nice concept, but it just needs a bit more polishing.
