"Dr Daina Taimina, a professor of mathematics at Cornell University, discovered that the best way to make models of hyperbolic surfaces is using crochet. Creating hyperbolic models using crochet is relatively simple: In each round, you add stitches at a constant rate. The more frequently stitches are added, the more quickly the model will ruffle up. You can use single crochet, half double, or double crochet as you choose (I was using double crochet). You can experiment with different yarn and hook sizes to achieve different looks. You can work with a single strand of yarn or a combination of yarns worked together."

This is an interesting project, but other than an exercise in Maths, I really dont see the purpose. Are they art? Are they a toy? Are they something else? The various forms are pretty, and I suppose you could use them as unique bath scrubbies. I would have appreciated some other suggestions from the designer, though. Sometimes Im too tired for much creativity.

These are great! I alter them slightly to crochet around an elastic and make scrunchies. You can get a nice variety of hair accessories that way. I imagine it would be a good pattern to use to make bath poufs as well You could sew a few together for a nice large pouf.
