Another central controller in the One Object at a Time world is the Object Creation Controller. Using this controller, visitors can combine objects from one or multiple designers to create a new composition for the world! These new "objects"--compositions, can act as interactive elements in the world; Visitors can walk and climb on them or sit by them! Add, undo, restart; using the "selfie!" button, take a selfie with your--or someone else's creation! One iteration at a time! These controllers are coded with a white and gold color combination.
