Andy Goldsworthy's "Walking Wall"

British sculptor Andy Goldsworthy has long been known for his unconventional approach to art. In an ongoing project at Kansas City's Nelson-Atkins Museum of Art, Goldsworthy has created a "walking wall," assembling and then disassembling the same limestone rocks, moving across the landscape of the museum's campus.

Bonnie has been a fan of Andy Goldsworthy for decades, but this project is very interesting - a "walking wall". Well done piece by PBS Newshour.
