So after having my tux droid for a while I decided to put it to good use, opposed to making it swear at my housemates, which no matter how entertaining it was did not seem very productive.
I decided to write a small script that would notify me when a build from Cruise Control.NET failed, or when a broken build has successfully been built. At the moment the tux droid speaks a simple message and flaps it wings a little.

The script uses the tux droid python API to make the noises and pulls down an Xml file, via CruiseControl.NET, using urllib and xml.dom, fairly simple stuff.

You can get a copy of the source, which might be more up-to-date, frm the bzr repository.
