Platypus Amoeba (Platy) is a reactive sculpture. It knows when someone is petting it and can indicate how it feels.
By petting Platy the user speaks to it. Platy uses lights and sound to speak to the user. This feedback can indicate happiness, sadness or other emotions. Users begin by trying only to initiate a response from the Platy but then quickly change their behavior to try to please it and get a happy response. The user is trying to control Platy by petting it in certain ways but Platy is controlling the user by indicating which way it would like to be pet.
