A coral reef in Pasadena
A detail from Margaret and Christine Wertheim's "Hyperbolic: Reefs, Rubbish and Reason," on view at the Art Center Williamson Gallery.
Five thousand crocheters from all over the world helped the twin sisters create a landlocked version of the world's coral reefs in an effort to bring to the public's attention the fragile condition of these submarine miracles due to global warming and the proliferation of plastics. The result of their work is fantastic. Go see it.
