Create OSX Notifications Xcode Style 4

How can I create floating, translucent, black Xcode 4 notifications and some other applications to notify users of events?

This screenshot shows the Xcode "Build Succeeded" notification.

Thanks in advance.

My answer here is How to implement a HUD-style window, such as the "Show in large type" address book , can serve as a good starting point. You would like to increase the radius on the rounded NSBezierPaththat was drawn and set the transparency below in the window so that it matches the transparency of the Xcode notification.

Take a look at the (Open Source) code for Growl .

This may give you some ideas.
