String figures
Zack noticed a copy of the Dover reprint of String Figures and How to Make Them at a bookstore, and I bought it for $1 (he already has two copies). This is an elaborate guide to Cat's Cradle and much more, from an era in which string figures and games were an active subject of anthropological research.
The book teaches you how to make the famous "Osage Diamonds"; maybe I will learn that. I also have the Dover book Fun With String, which Zack has never seen. Ah, the simple pleasures people enjoyed before the transistor...
