Peggy helps you to create GTK applications that run out-of-the-egg. It offers functions to load resources (like .glade files, images, and locales) from a zipped or unzipped egg. It is a thin layer on top of setuptools and PyGtk. It doesn't do anything very fancy, but it can save you from reading some documentation.
Musca is a simple window manager for X allowing both tiling and stacking modes. It is similar to ratpoison but more friendly to the mouse and using a simpler keyboard navigation. There are no built in status bars, panels, or window decorations save for thin window borders to indicate focus. Window navigation can be mouse click to focus or entirely keyboard driven. Window tiling is manual but simple, and there are no restrictions on how you divide up the screen. It uses dwm's dmenu utility for launching apps and running various built in commands not mapped to hot keys.
