As a child, Price used Pinky balls while growing up in New York playing kick-the-can and stickball in the streets. They are lightweight, inexpensive, balls that are the imperfect, rejected, rubber cores of tennis balls that are sold rather than being thrown away. Price began building structures with them several years ago after reading about, and identifying with, their origins and subsequently becoming enchanted with their color and the visual associations with biological function, manu- facturing and sense of play.
