NexusKang just got an update thanks to Kmobs, which adds support for Android 2.3 plus the Nexus S live wallpaper as well as a few minor bug fixes.
The app is definitely worth checking out if you're a fan of the original live wallpaper for the Nexus One, because it allows you to take that basic design and totally customize it. Users can choose their own background image and even customize the colors that streak around the screen. Of course, if you just want to get the Nexus S live wallpaper, you can now choose that one too.
You can get NexusKang by heading over to AppBrain or by scanning the QR code.
