I was watching a recorded edition of Beyond Tomorrow (from Science Channel) and saw an awesome-looking motorcyle helmet, the Reevu. It has a series of polycarbonate reflectors that take light coming into the helmet from the back, reflect it over the rider’s head, and display it on a small mirror just above the visor in the front, so you always have a view to your rear (and even sides, byt turning your head slightly), and don’t have to take your eyes off the road as long, or at all.

They run about $500 in the UK, and I want one. It’s in the same price range as Shoei and other mid-high end helmets.
