I've had this idea for a while, and only recently got around to drawing it up. I consider this to be a bit of a life-saver - when you're making a right turn and some knob goes for the overtake, you'll see it coming.
If you want to get a rough idea of what's going on behind you, you could just stick a hand up and check (be as subtle as you want).
It's also better than a standard wing mirror on your bar-end or down tube in that you could move your hand around for a better view.
I wouldn't know where to start as far as actually making such a thing, but decided I'd see what you thought of this idea.
At the risk of turning this concept into an overengineered sort of Swiss Army knife, it could also come with a flashing amber light, powered by piezoelectrics or solar, and maybe even triggered by an accelerometer. That would make it expensive, but possibly a handy gadget.
