XPTracker is a radical alternative agile planning tool aimed at keeping out of your way and making sure you can see the stuff you care about at a glance. Included in this tool is a very advanced search system based on Lucene, an easy-to-use planning system based on Queues, and a customizable reporting engine (with burndown/scope creep charts) called Timelines.
BART Tracker reports on arriving San Francisco area BART trains in real time, using a system tray icon. It uses BART's new "Estimated Arrivals" or "BART System Status" feature, which reports on the current up-to-the-minute status of arriving trains at every BART station. It requires Java 6.
Infonomix is a project management system similar to Trac, written in PHP and using XSLT. It is designed more for professional services tasks, like graphic design and Web development. It also keeps track of time using a time clock system, and time can be assigned to tasks, projects, or clients.
