Do you have a modded Xbox? Do you run XBMC? Forget the PMIII skin, go to the Aeon skin! This skin is made for HDTV systems, so if you have a 720P or 1080i HDTV screen, you will see the beautifulness of this skin.
The coolest part is that you can assign different picture backdrops for each selection (Movies, TV Shows, Pictures, etc.) and its all random. A post about it isn’t going to do it justice. Check out the skin at www.aeonproject.com
