Fun with laces

Leave it to me to find others with hyper-fixations and math skills far superior to my own. Leave it to my mentors to teach an entire class on the subject. I give you, Professor Shoelace himself. The book is somewhat of a collector's item now. But when at my worst, I couldn't tie a shoelace. Never take your dexterity for granted, and never think it has to stop when your hands do. This pattern was always a favorite and allowed me to not unlace much.
