The static site generator for my website: http://beza1e1.tuxen.de/gen.py

A news bot: https://github.com/qznc/mrktws-news (the output is public, does it count?)

A TiddlyWiki server: https://github.com/qznc/tiddlywiki-py

Such stuff usually costs me a few frantic evenings to build the first version and then minor maintenance.
