Thomas Bayrle has been pursuing the concept of developing 'superstructures' from encapsulated image patterns since the 1960s. He uses it for drawings, photocopy-montages or film animations, at first needing to work painstakingly by hand. It is now possible to process images like this more or less automatically by computer. Thomas Bayrle meets his grandson in the computer-animated video '(b)alt' and uses interconnecting, superimposed image patters to address the sequence of human generations sensually as well as metaphorically.
