There is a posting on Ning about hyperbolic tatting which was inspired by the hyperbolic crochet word done a while ago. The links on the page are also interesting since many of them lead to the Hyperbolic Crochet Coral Reef which is beautiful. See: http://api.ning.com/files/7K-JVVxwVhh4LGvReFO018O*M*lVkVxiCkKDXgkvZES9uImRI9DR6d5*5E-Te54YQgM07nM*LFJxlaKHH-5w6iU-Gm28GnaB/HyperbolicTatting.pdf
Enjoy!
