Some may remember when I showed a visit to the roof of the Metropolitan Museum of Art a few years back. I visited again recently and they are showing a sculpture by the artist Roxy Paine called Maelstrom (2009). It's very cool! This is some info from the museum's website: "The latest in a diverse body of work, this sculpture is one of the artist’s Dendroids based on systems such as vascular networks, tree roots, industrial piping, and fungal mycelia. Set against Central Park and its architectural backdrop, the installation explores the interplay between the natural world and the built environment amid nature’s inherently chaotic processes."
