Today I was using the search feature in Y PPA Manager to see if some of the applications that don't have a PPA finally got one and found a PPA for Wingpanel. It's not an official PPA but you can use it to easily install Wingpanel.
For those who don't know, Wingpanel is a "super sexy space-saving top panel" created by the Elementary team that displays the Ubuntu indicators. Because it doesn't take the whole width of the screen and maximized windows go below it, it can save a lot of vertical screen space.
Here is a short video recorded by Seif with Wingpanel in action:
To install Wingpanel in Ubuntu 10.10 Maverick Meerkat from the Ripps Misc. PPA, use the following commands:
sudo add-apt-repository ppa:ripps818/wingpanel sudo apt-get update sudo apt-get install wingpanel
Then press ALT + F2 and type "wingpanel" to run it.
Note: you may want to either move or completely delete the top panel if you decide to use Wingpanel.
