The installation is called "Sisyphus". It is named after the Greek myth of the tortured soul who is forced to roll a boulder up a mountain each day, only to have it continuously roll back down to the bottom.
Sisyphus consists of a metal ball that guided through a surface covered in sand, presumably using computer-guided magnets underneath the table.
Watching this system in action brings to mind the quote by Arthur C. Clarke, "Any sufficiently advanced technology is indistinguishable from magic."
It is a modern take on the Zen art of rock & sand gardens, with similarly profound meditative qualities.
It is also reminiscent of Tibetan sand mandalas, which are intricate spiritual designs made of colored sand. These creations are ritually swept up & the sand dispersed after they are finished, to symbolize the impermanent nature of existence.
