A toroid is a donut shaped object, and a snark is an imaginary animal that is difficult to track down. The website “toroidal snark” has many great links about the relationship between math and knitting. Carolyn Yackel and Sarah-Marie Belcastro have put together this wonderful set of links which will give endless examples of patterns to choose from, or colour combinations, or objects that can be knitted. There are also links to talks about math and knitting. This is a great hub of possibilities.
