pyDirStat is a small tool to view statistical information about a directory. It will generate a view of all files contained in a directory (and subdirectories) with rectangles. Each rectangular area is proportional to the file sizes. It's useful for viewing disk usage with graphics. It's a non-interactive command-line tool that will generate HTML or SVG or SWF files. On Windows, it also runs as a shell extension.
pyrfeed is an RSS/Atom client that can support several ways of connecting to feeds. It can use GoogleReader directly or via a caching database for offline browsing. It aims to use other ways of fetching RSS/Atom feed (directly like most RSS/ Atom clients, or using other Web sites). It also supports several GUIs. The main UI (aui) is based on the "aui" components of the wxWidget projet. There is also a TTY command line interface.
