PyNeko has been extended a little bit - now, we can build walls between cells.

I have introduced the first Python keyword, `def' in chapter 5 (neko learns some new tricks). Now, it is time to introduce variables and iteration. The variables-as-name-tags approach (rather than values-in-boxes) seems to be better, as it provides consistency (and does not hinder understanding a bit). Question is - whether to go for generative recursion (like htdp.org) or explicit looping? Will kids understand self-reference?
I have added a help wanted section.
The `Hardware hacking with Debian' book has been updated with a small appendix.
