In the year 3000, surgeons should be able to graft animal body parts onto our willing flesh. But, let's be real, aside from a reanimated Walt Disney (ok, not really), most of us won't live to see that scifi horror-filled day. Filling in, for the time being, is a nifty Arduino hack from the mind of one Artharis that breathes erratic life into a 3D printed tail. Its clumsy flailing is more disturbed-dragon-with-ADHD than aroused puppy, but we'll take what we can get for now. Shame, though, that Halloween's already come and gone, otherwise this would've made for a nice house party icebreaker. Peep the spastic animatronic in motion after the break.
