Spanish designer Héctor Serrano hit on something with his temporary tattoos that make hands look like puppets.

For generations people have used their hands to express themselves--including using hands as puppets. Some people just use their hand, some people use their hands to make a shadow puppet, while other people put a sock puppet over the hand.

Héctor Serrano’s temporary tattoo puppets come in eight patterns which can be applied to the hand using water. They’re a fun way to entertain infants and babies, and the immature at heart.
