I was so inspired by the show at the Cultural Center that I tried some hyperbolic crochet and coral reef designs last weekend. I made a hyperbolic coral and a attached two anemonies and some seaweed to a flat stone from the Lake Michigan dunes. The images are a little odd--my photographs were quite out of focus (obviously I need some practice) so last night I scanned the 3-dimensional objects and the images were much better, if a little squashed.
The website for the Hyperbolic Crochet Reef that visited Chicago is http://www.theiff.org/reef/index.html. There are increcible photos and some instructions there.
There are about three days left for the Chicago exhibition, which also includes a Chicago-made crochet coral reef. http://tinyurl.com/yqwyg
