I read a lovely book this winter called Knitting for Peace: Make the World A Better Place One Stitch at a Time which profiles 28 stories of people and organizations who are using knitting for good. One of the organizations, Afghans for Afghans, collects knitted goods for orphanages, clinics and children's hospitals in Afghanistan, and has a Frappr map that I thought was really sweet.  When you view it, it automatically rotates through the different knitters on the map and shows a pop window with a photo and a message from each one like, "I am a musician who likes to knit socks."
