BadWM is a minimalistic window manager for the X Window System licensed under the GNU General Public License.
The latest release of BadWM is 0.1.1. Since it is not actively maintained any more, I put the latest code online.
If you want to take over the project do not hesitate to send me an e-mail.
Mailinglists: BadWM-users and BadWM-devel.
There are some older screenshots available.
Alexander Kremer wrote some add-ons to BadWM which you can find here.
