We mentioned it briefly but the new Windows Phone Xbox Live game Chickens Can't Fly now has its own Windows 7 theme. It joins other gaming title themes such as Fruit Ninja, Angry Birds and the Xbox Kinect game Gunstringer.
The Chickens Can't Fly theme includes wallpapers, sounds, and colors (no screen saver). The graphics look great and the sounds unique. But I have to admit it takes some time to get used to the chicken cluck as your alert sound.
You can find the Chickens Can't Fly Windows 7 theme pack here at the Windows download page.
