Looking for something fun to do this Halloween?  How about scaring the crap out of people everywhere.  Alton Porter has a pretty good setup for this.  It looks like adding a lightweight skull (either wire-frame or Styrofoam), some LED eyes, and some tattered cloth.  Just make sure you don’t interfere with the blades, nobody wants you to crash your quad!

This would be amazingly cool with a swarm of small drones.  Great idea.
