Crochet your own coral reef

To get inspired you can virtually dive into the Coral Sea and have a look around the Great Barrier Reef with Seaview Underwater Virtual Tour. Seaview will soon be a part of GoogleEarth, but is already available on this website. It's well worth looking at snorkeling around.

There are tons of images of crochet coral on Flickr.

Also there is the Hyperbolic Crochet Coral Reef,  "a woolly celebration of the intersection of higher geometry and feminine handicraft, and a testimony to the disappearing wonders of the marine world"  created by Margaret and Christine Wertheim. Find out how start your own satelite reef.
