So I recently watched a marvelous TEDTalks called Crochet a Coral Reef and I was really inspired to participate. Creating a hyperbolic math model with crochet is very cool, and turning it into a lifelike coral reef display is even cooler!
I started one today, and half a skein later, I am really amazed at how simple it is to make some of the basic coral shapes, and how beautiful it is! Currently, I'm just using the yarn I had on hand, some green and brown variegated synthetic. It makes a lovely basic coral! Once I finish a piece or two, I will post pictures of what I'm doing. In the meantime, check out what other people around the world have made!
