Not hyperbolic crochet - exhibition of large crystal precipitates.
What you see on the photograph is pretty much a hard core Chemistry exercise. These colorful masses are the result of the precipitation of a solid salt in a supersaturated solution, followed by crystal growth. First, some the crystalline nuclei are formed in a process called nucleation. Then, there is an ordered growth of these nuclei into larger well-formed crystals. But, can crystal growth and hyperbolic space be related?
Hyperbolic crochet reef: a woolly wonder (exhibition at the Science Gallery in Dublin)
During Spring 2010, over 50 000 visitors came to the Science Gallery, in Dublin (Ireland), to see the Hyperbolic crochet reef: a woolly wonder, an exhibition curated by the Institute For Figuring. This show marked the first time the Reef was been exhibited at a science institution and the installation included several new features.
Moebius strip (1)
A Moebius strip is a surface with only one side and only one boundary component. It is quite easy to do and combine with hyperbolic crochet. Once the strip is done, all you have to do is crochet along the boundary. This one was done with a small diameter, and two different types of threads. The ration was 4:5 (one increase in every 5th stitch).
Pseudosphere (3)
A pseudosphere, done with different random ratios. For more dramatic effect, I used a very thin hook and a double strand to make it rigid.
Pseudosphere (2)
A pseudosphere done with ratio of 1:1 (increase in every stich). One stich of the initial row was mutated into green.
Pseudosphere (1)
It looks live a very simple pseudosphere, but I used 3 different ratios (increases in every given stich).
On the study of hyperbolic geometry
For God's sake, please give it up. Fear it no less than the sensual passions, because it, too, may take up all your time and deprive you of your health, peace of mind and happiness in life.
—Wolfgang Bolyai (1775-1856) to his son Janos Bolyai regarding the study of hyperbolic geometry

This is how it started... A random talk on TED.
