 The frilly curling shapes of the "Crochet Reef" are manifestations of hyperbolic surfaces, the same forms made by living reef organisms.The ability to crochet such forms was discovered in 1997 by Daina Taimiņa, a Cornell University mathematician.Through their work with IFF, the Wertheim sisters have created exhibitions on scientific and mathematical themes at art galleries and science museums around the world, including the 2019 Venice Biennale, Andy Warhol Museum in Pittsburgh, the Santa Monica Museum of Art, the Hayward Gallery, London, Art Center College of Design in Pasadena, California, 
Machine Project, the Museum of Jurassic Technology in Los Angeles,
