 Since its beginning in 2005,"Crochet Coral Reef" has expanded into a constellation of individual reefs including a "Bleached Reef", a "Toxic Reef" made of video-tape and plastic, a "Branched Anemone Garden", and a giant "Coral Forest" – consisting of six large-scale sculptures, three crocheted from yarn and three from plastic.The plastic works are inspired by the Great Pacific Garbage Patch, a gigantic gyre of plastic debris in the Pacific Ocean.Inspired by and working with Jeannine Mosely, a software engineer and origami artist, Margaret Wertheim curated a project at the University of Southern California to create a giant model of a fractal, constructed from 48,912 business cards.
