Blackbox needs developers desperately.
If you can code anything, from a plugin to an improvement on an old open source build to a completely new build (we wish) than please come in touch with us, either on boxshots/lostinthebox/bb4win
You can help this WM/shell and this community find their rightful place. There is some interest expressed, but we do need more and we need to fight back if we want Blackbox WM to stay afloat. Plus, we would welcome ideas in the lostinthebox forums (yes, they are open to everyone)
Blackbox is the fast, lightweight window manager for the X System you have been looking for, without all those annoying library dependencies.
Blackbox is built with C++ and contains completely original code (even though the graphics implementation is similar to that of WindowMaker).
Fluxbox and Openbox are both, based off of Blackbox.
