It may look like a confusing mess, but this hanging, U-shaped blob is actually an art installation that was carefully pieced together using individual, brightly colored plastic bags.
Pascale Marthine Tayou is a contemporary artist from Cameroon who uses commonplace objects in his work, and plastic bags are one of his preferred mediums. Here, he used a huge number of them to make a colorful installation that's on display now at the Macro Museum in Rome through April 1, 2013. At over 30-feet high, Plastic Bags is the centerpiece for Tayou's larger exhibit at Macro called Secret Garden.
I can't imagine the level of patience it would take to build something like this with plastic bags, so that's a feat all by itself, but Tayou's sculpture does hold larger significance: it's a representation of consumerism and homelessness in modern society.
