Karl G. Siewert is a librarian (again and again...) and a yo-yo enthusiast. In his words: “I began calling what I do “yoyology” a long time ago. It sums up my philosophy that yo-yo play is both a diverting pursuit and an almost scientific discipline. When I’m playing with a yo-yo or other skill toy, I’m performing a physical activity that requires precision and grace, but I’m also thinking, consciously or unconsciously, about things like weight, spin, momentum, gravity, and tension. At its best, yoyology combines it all.”
Obvisiously he is NOT a webdesigner or an illustrator.
