Duality is the starting point for this collection of Luyken-like associations: his two sons at different locations perform small actions; signed a cross returns as three-dimensional shape; indoor and outdoor spaces. The soundtrack features the sounds of drumming on metal. The title lapels to Luyken's two sons.
