Nixie is currently a project and what it exactly does is that it is capable of launching on its own from your wrist and start taking snaps or videos of you. The Nixie is powered by Intel Edison chip and it is an interesting concept yet a rather cool one as well.
The video of the Nixie drone below shows a lot more action. Unlike other video recording drones, the Nixie seems like a very light weight drone and will have the ability to wrap around a human wrist and launch on its own when instructed.
The Nixie is also capable of detecting the person being photographed. This might be the end of extended arms in plenty of selfie shots that keep popping every second.
