The Air installation will be filled with light activated pinwheels that spin faster when there is less light and slower when there is more light. The hope is that this installation will contain 200-300 pinwheels all in the same location. The intention is for users to move through the environment, with their movement serving as the impetus that will trigger the pinwheels to move. This will be accomplished by controlling the light sources in the room so that as users move through the space they will create shadows. These shadows will act as the mechanism for triggering the pinwheels to move faster or slower. Creating the pinwheel design was accomplished by combining several simple electrical components together in a battery powered circuit. For more information about the specifics of the design and circuit, see below.​
