ZENTRUM is a dynamic, endlessly running abstract animation made of structural elements and random codes. The random generator ensures that each endless loop is unique. For ZENTRUM, Franke had to make do with the limited computing capacity that a home computer offered at the time. Despite this limitation, it was important to him to develop moving sequences even in his first programs for the Apple II. He considered the movement to be a pioneering digital innovation. The combination of dynamic image sequences and music, as well as the interactivity, were already groundbreaking in his MONDRIAN program code, developed in 1979 for the Texas Instruments home computer.
