Did you know you can create your own PS3 themes. There's even a PlayStation 3 Custom Theme downloadable pack to get you started.
Theme creation ranges from simple things like editing the kit icons a bit to starting from scratch. The EU PlayStation blog has a bunch of tips on how to make your own. There's an example that shows how a Japanese Manga theme was created, custom XMB icons and all.
I have some Destructoid custom backgrounds but I'd love to see a full-blow Destructoid PS3 theme, complete with all the little icons and sounds. Any takers?
