Artist Joe Mangrum (previously) was just in Zuidlaren, Netherlands, where he was commissioned by the Doe Museum to create 8 temporary sand paintings over a period of 11 days. All of Mangrum’s paintings are spontaneous and evolve as he works, a grueling physical process that involves dozens of revolutions around the artwork as he adds new details and flourishes by pouring brightly colored sand. All eight artworks were photographed as he worked and turned into time-lapse videos, three of which are included here. The sand paintings will remain on view through October 30, 2015.
