There's a manga about a Ubuntu Linux, published under a Creative Commons license. Self-described as a "Ubuntu romantic school comedy". It's the perfect triangle of linux, copyleft, and Japanese popular culture!
I've put left-to-right versions (i.e. standard North American cartoon reading style) on my blog, as is permitted under the Creative Commons: Attribution-NonCommercial license.

I normally wouldn't post such a blog-ish blog post, but this was just too awesome to resist.
