Gift thoughts for the holidays

I am a fan of nearly every kind of small aircraft, but I might draw the line here:


It's a personal helicopter, really two rotors on a hat. Action video here, from Makezine (thanks to Dave Proffer). As it happens, one of my upcoming New Year's resolutions is to get back into aviation actively. But avoiding this hat-helo would be consistent with two of my rules for a happy flying career: Don't fly anything that's not factory-built (sorry, home-crafters); and fly only airplanes, not helicopters. More on all of this another time.
