This mindmap explains some of the ideas and concepts in more detail.
It can be viewed with the "freeplane" mind mapping software.
("freemind" works as well, but will mess up some of the formatting)
note by the committer: this mindmap was really work in progress.
Christoph shared it with me while in discussion. I'll place it
here in the git history, since it might be interesting to se
how the thoughts evolved. Isn't that what mindmaps are all about?
