People ask me why I made that. It's not clear. (Laughter) But I thought it'd be neat for the square to respond to me, and my kids were small then, and my kids would play with these things, like, "Aaah," you know, they would say, "Daddy, aaah, aaah." You know, like that.
Man fragte mich, warum ich das gemacht habe. Man kann nicht sicher sein. (Lachen) Aber ich dachte, es wäre nett,  wenn das Quadrat auf mich reagiert, und damals waren meine Kinder  noch klein und spielten damit: "Aaaah!" "Papa, aaah, aaah."
