Growl
Growl is a system notification application that resides in System Preferences. “Notifications are a way for your applications to provide you with new information, without you having to switch from the application you’re already in.” More and more developers are adding support for Growl. Applications such as Adium, Transmission, Max, and Transmit use Growl.
Growl is extremely customizable. When installed, take a gander in System Preferences and a new icon for Growl will appear at the bottom. Here, I can choose from a variety of display styles, enable specific notifications from different Applications, and even stylize the notifications.

Growl is def an awesome app. What is even cooler is how it will auto detect if a new application is supported by growl, and then start showing notifications for it.
I def recommend going in and customizing which notifications you want to show up for each application because some can get a bit annoying.
