Interesting and cool promo video, I thought the chick who phoned him was going to talk him out of jumping for a moment or two.
Looks like an adaptation of a fighter pilots Heads up Display. The Govt would see it as distracting so like cellphones we would not be allowed to use them while driving but fighter pilots use them while flying and they go much faster? Wonder if it can be retro fitted to my prescription specs.
Oh hang on a minute, this is probably just another one of those Google experimental technologies that we all get excited about but then they discontinue for some obscure reason!
Beam me up Scotty!
