Ian's Shoelace Site - Bringing you the fun, fashion & science of shoelacesSome of the stuff there looks genuinely useful. Most of it is far more about shoelaces than I ever wanted to know :)
The site was created by Ian Fieggen, the self-styled “Professor Shoelace”. He has written a book (“Laces”, now out of print), and has apps about lacing for iPhones and Droids. He apparently now supports himself through the web site and apps. Oh, and did I mention that he's Australian (as is Simon)?
