I started working on getting the GNOME Shell - Zeitgeist work by Federico's GSoC student Akshay Gupta (kitallis) more stable and visually appealing. I am not a designer but I think this is not that bad... I hope I can get Hylke or Garrett to look at it with me during the week.
Currently its an extension you can get from here... (You will need to install the latest stable Zeitgeist)
Here are some screen-shots. I will be working on it more this week and expect a nice git branch with some final touches (I will be changing some functionality to be more convenient)
