"Randomized skins
WindowBlinds enables you to change skins randomly at timed intervals. Your desktop will never be boring again when you are greeted with a new skin every time you logon."

OK, found it. There's a tiny cogwheel icon at the top right. Unable to delete this post, or would have. Thank you.
