EVO 3D dev Eugene373 has recently ported the Sony Ericsson Arc launcher, and even though all the kinks haven't been worked out yet, he's confident that the very minor bugs shouldn't be enough to stop you from using this as your daily launcher.
The launcher has seven home screens, as well as four customizable app shortcuts across the bottom of the home screen. The app drawer has also received a nice refresh, including a transparent background and left-right swiping.
In case new Sense skins aren't quite enough of a change for you, perhaps this new launcher will be. Just keep in mind that you will need to install the apk as a system app using either ADB or an app like Root Explorer. If you decide to give this a spin, be sure to let us know what you think![AndroidSPIN Forums]
