Bright, synthetic color meets natural materials in "Wake," a land art installation by Michigan artist Michael McGillis. The semi-subterranean piece transforms the relatively mundane sight of giant wood piles into a surprisingly beautiful and interactive work of art. Originally installed at Minnesota's Franconia Sculpture Park in 2006, the installation consists of a 95-foot long trench lined with crosscut logs. The ends of the logs are painted various shades of purple, inviting viewers to walk through. Really cool.
