Ever use the Myvu Crystal? It’s a pair of glasses that has a built-in VGA-quality display. The idea here is that you connect the Crystal to your portable media player or cellphone and you can take immersive audio/video with you wherever you go. That’s the idea, but like I said I haven’t used them so I can’t speak to how well they work. Doug seemed to like it, though.

In any event (which is my latest crutch of a phrase, you may have noticed) the Crystal is now fully compatible with the iPhone 3G. You need to buy a separate $25 cable to get your Crystal and iPhone to play nice.
