At work one day, on the phone suffering through a terribly long conference call, I began to sketch on a post it note... a crude drawing of Donatello the ninja turtle. I colored it with highlighter and sent the picture to my daughter. She loved it, and began requesting other heroes each day. It took on a life of its own, and now I'm well into year 2. This is the full roster from the first 360 post it sketches.
