In 2005 the sisters Christine and Margaret Wetheim started to build the hyperbolic crochet reef project. They wanted highlight the damage done to coral reefs due to global warming using craft as the launch pad. This has been a phenomenal success with more than 8,000 people participating in coral reefs projects around the world, including a Sydney reef in 2009.
But what is meant by hyperbolic? How did crochet get involved? In this talk we see the highlights of the 2000 year history of hyperbolic geometry that led to mathematician Daina Taimina realising that she could crochet these objects.
