Gswitch automatically changes your GNOME desktop background every so often. The backgrounds are displayed randomly. All background images and style settings are sourced from your list of backgrounds as configured in "System > Preferences > Appearance". By default, images are switched after 20 minutes. Although the images are shown randomly, every image will be shown at least once before you see any repeats.
checkcopy is a GUI tool to copy the files and directories to some destination while creating checksums and/or verifying them. It reads all the checksum files, then reads in each file to copy it to the destination. If a checksum is present for the file, it will be verified, otherwise the checksum is written out to disk.
Stigma is a client for connecting to Omegle. It currently supports all of the non-video Web interface.

There are no plans yet to get more than just the text version, but most of the text-chat functionality is usable and stable already.

GTK+ Recent Files Scrubber is a compact, lightweight Python script which uses GTK's RecentManager to watch for updates to all globally-available "Recently Used" lists (the ones which appear in Open dialogs and the like) and filter out anything in the folders you blacklist. Blacklist entries are hashed to make reading the blacklist not worth the effort.
