The Swirling Brain noticed an io9 post from a while back with some cool (or creepy perhaps) disembodied humanoid robot arms. They are known as the Ondz clapping robots and were created by Masato Takahashi of Keio University. His goal was to make "multipurpose hand-clapping machines" that would sound like authentic human applause, though other purposes ranging from telepresence clapping to spanking machines have been suggested. Read on to see more video of the clapping robots in action.
