ScrudgeWare is a 100% GPL (or other freely licensed) GNU/Linux distro designed to build a simple ("bare bones") system on which the user can add any software they choose. As part of the basic framework, a system will be devised to allow users to share their customizations (or custom distros).
Hackedbox is a stripped down version of Blackbox, the X11 window manager. The tool bar and slit have been removed, as the goal of Hackedbox is to be a small "feature-set" window manager with no bloat. There are no plans to add any functionality, only bugfixes and speed enhancements whenever possible.
Spkgtool is a software management system that uses symbolic links for maintaining packages and a "ports" style backend for building package from source tarballs. It has its own built linking application, but it also can act as a GUI frontend to your favorite symbolic link package system (supporting graft, epkg, and stow). It is written with bash scripts and Makefiles. The GUI is dialog and Xdialog (depending on your environment). Aside from building ports, it will also build and install "GNU-friendly" source tarballs.
