Amigurumi and all that jazz…

My 26 year-old came strolling into my room with Hansi Singh's "Amigurumi Knits" in hand, completely gaga over the sea star, which blew me away. He's now into the first year of his MS in Biomed.  Think I can hook him into knitting via math? Gotta have someone to share this yarnstash with! 🙂
