The Bubbling Load Monitor (or "Bubblemon" for short) is a system load monitor for the GNOME panel. It looks like a vial containing water. The water level indicates how much (electronic) memory is in use. The color of the liquid indicates how much swap space is used. The amount of bubbles reflects the system CPU load. A message in a bottle indicates there is unread mail. A reed-like graph shows I/O load. On multi-core systems the CPU with the highest load will bubble in the middle, and the others on the sides, so it's possible to see how well load gets distributed between CPUs.
ChBg is for changing desktop backgrounds in a given period. It can render images with 10 modes (such as tiled, centered, scaled, etc.). It uses Imlib1, Imlib2, or gdk_pixbuf for loading images, so it supports many image formats. ChBg has a windowed setup program, is able to load setup files, can be used as slideshow picture previewer in its own window or as a desktop background, and can be used as screensaver or as an xscreensaver hack. It has a dialog for fast previewing of pictures and very usable thumbnail previews.
Cheops-ng is a network management tool for mapping and monitoring your network. It has host/network discovery functionality and OS detection, and does a port scan of each computer to tell what services are running. It can probe FTP, HTTP, ssh, email (port 25), news, IMAP, and VNC to see what version and type of server is running on those ports.
Conglomerate will be a system for authoring, storing, transforming, and generally working with structured information like XML/SGML (yes, it will do DocBook, or any other DTD you care to throw at it). It's not a finished product, but there is working code with the basic functionality, screenshots, and ample descriptions of the system.
