Possessed hand – Digital human

News from the future, they’re proposing this as a way to help learn to play a musical instrument. Mortal fools, wasting their time playing musical instruments, when they could be juggling.
More info, only in Japan.
One day, we won’t need to practice contact juggling, we will download tricks directly into our brain implants. Ahead of the game, MoM have a new introductory offer: We will sell you palm spinning 10 balls-in-1 hand for just £10. (You supply the balls).
