Projects exist in a time continuum. They start at some point, exist for an amount of time and then reach the deadline (hopefully). Keeping this in mind, we developed a timeline view to show progress and tasks – you can preview it here. 
This project is developed as a part of a bigger application – 5pm™. It’s a second generation project management tool, developed by our QG|Software division.
We plan to add editing capabilities to the timeline (imagine just dragging your tasks around) and other cool features.
To find more about this project and track its development, go to www.5pmweb.com. The beta release is coming out soon.
I would recommend that you all fill the test calendar with some projects. Can’t really see the entire concept if there are no existing projects to view. That or some detailed jpegs.
