The Nixie wearable drone is controlled by your phone and, interestingly enough, started out as a different type of wearable - something that you put on your face like glasses. I agree that putting it on your wrist as a wearable band makes a lot more sense. If Nixie wins the Intel Make It Wearable competition, they will get another $500,000 to make their product a reality... and perhaps people can then start working on flying timepieces
