I use the pit dynamic one, pretty bad ass theme. I've yet to see any other PS3 themes I like; still amazed that it was free. I've noticed there's a bit of confusion on how to actually get the theme though, so hopefully this will sum things up.
Step 1. Go to
http://www.ps3-themes.com/ on your PS3
Step 2. Search "Mortal Kombat pit"
Step 3. Click on "Download Now"; it'll download as a PS3 theme as opposed to having to use a flash drive and all that mess.
