In a 21st century take on the traditional Zen sand garden, artist Bruce Shapiro invented the Sisyphus Machine, an elaborate kinetic drawing machine that uses magnets to drag rolling steel marbles through a thin layer of sand to create complicated mandala-like patterns. 

Shapiro, who was once a practicing physician, has spent the better part of 25 years experimenting with computerized motion control and many of his Sisyphus Machines have been installed in locations around the world including a large device in Switzerland back in 2003 and at Questacon in Canberra, Australia in 2013.
