Manga about running Ubuntu

Ubunchu, a manga-style comic for kids about the joys of running the Ubuntu Linux operating system (this post is being composed on an Ubuntu laptop -- the only OS I've used for a couple years now*). It's a free, CC-licensed PDF, and it's been translated into a very large number of languages, and there are more editions to come.

*Yes, I know I haven't written up my notes on switching to Ubuntu yet. I will, someday.
