Custom Launcher Icons used to be known as LauncherPro Icons, but they decided the name is too restrictive, as the icons and docks are now universally applicable (just about). They also completely revamped the interface. The idea is still the same: pay for this app, and you can much more easily access the icons and docks in their collection. You could download them off their website one at a time, but why? :)
As this is a paid app, and you should encourage the artists to make more... You really should get it.
