Blackbox is an original window manager, sharing no code with any others. It's designed to be fairly small and minimal, making it particularly suited to less powerful computers. It doesn't support images, other than generated gradients, but it does support multiple desktops and is NetWM compliant, making it compatible with KDE and GNOME.
Here are some links to Blackbox websites:

- Blackhome: a utility for applying Blackbox themes to applications.
- black2openbox: a web page for converting Blackbox menu configuration files to the OpenBox standard.
