Wrist Rocket

That’s right, friends, a quadcopter camera that you wear on your wrist.  THIS IS WHAT I WANT FOR NEWTONMASS, PEOPLE!  The prototype (not the rendering above) looks like it would actually work pretty well:

The promo video from their website hints at uses, which I have been advocating for years, like a follow me camera for safety and bragging:

Nixie is powered by Intel’s Edison kit, which is both small enough and affordable enough to fit inside such a small device. And devices like this will only get smaller.

As far as I can tell, Star Trek did not think of this in the 1960s.  Of course the Next Generation did, but we already had cell phones by then so no points for out-of-the-box thinking for them.
