Hyberbolic Crochet (via podkins)
Hyperbolic Crochet is the name given to applying a mathematical principle to crochet patterns. A hyperbolic plane expands exponentially from any point on its surface, always curving away from itself. You can easily crochet a hyperbolic surface by increasing at a constant rate throughout the piece.
Hyperbolic growth in nature gives rise to the ruffled shapes of coral, kelp, and sea anemone. The Institute for Figuring created the concept of the Coral Reef with hyperbolic crochet and have been developing this concept since 2005.
