My version of the character Ada from "Ada & Zangemann", a Creative Commons license (BY-SA) book for children and a funny story about Free/Libre and Open-Source. It's written by Matthias Kirschner and illustrated by Sandra Brandstätter. It is great to see new characters in the Free Culture, especially because Ada is so cool.
