The Analog Digital Clock by Maarten Baas (Arnsberg, 1978) is a digital clock, in which the numbers are manually changed by painters every minute. The clock is part of the ‘Real Time’ series: four clocks (including the Schiphol clock, Grandfather clocks and the sweeper’s klok) that display 12-hour filmed performances indicating the time. In real time, Maarten Baas expresses his perception of time: how it passes and how valuable and infinite time is.
