Do you use Launcher Pro for your launcher? Of course you do (and if not, you should, dangit, and no, I’m not biased at all :P). One of the nifty things you can do with Launcher Pro is customize the dock with all manner of backgrounds and icons in order to further prettify your Android phone and make your iPhone friends jealous. ;)
That being said, the good folks at XDA-Developers have posted about a new set of icons for Launcher Pro’s dock called Knockout made by user skribblize, and boy are they sharp. As you can see in the example above, many icons are included, such as:
music player (2)
task killer (2)
There are seven icon packs in all, including Water (as shown above), Fire, Earth, Wind and more. Head over to the XDA-Developers thread above for examples of the other icon sets and for download links as well, and enjoy!
