140Charbooks
140Charbooks is a Twitter project together with @dosinga. The idea is to tweet book reviews and have a script determine who to follow based on title and author of the book we tweeted about. To make sure the number of friends does not get too high, the script also unfollows people based on an algorithm.

Ant Arena is a project I did a long time ago together with Douwe Osinga. The idea is to have an arena where virtual ant communities fight for dominance. Users (programmers) can create their own ant communities by writing a piece of Javascript code and have it compete against the rest.
Recently Willem Mulder wrote a webbased version of Ant Arena called Jabe (Javascriptbeest).
