Amsterdam airport clock has hands painted in real-time

A clock installed at Amsterdam's Schiphol airport features an illusion of a man erasing and redrawing the clock's hands every minute from inside a box. The Schiphol Clock, designed by Dutch artist Maarten Baas, is actually a 12-hour video performance playing on loop on the screen of the box. Notably, Baas was inspired by people who work at the airport.
