Daffy, I liked it for the very "abstract-ness" of it myself.
I don't really consider it "busy" though. There were plenty of busy skins there, but I found they were generally the ones with more distinct images and patterns, and to me, the abstract nature of this detracted from the busy-ness.... Or maybe that's just me.
But yeah, I threw on the back simply because I sometimes pull my Kindle out of the case Amazon case I have for it and read it nekkid. So it's nice not having the cold metal back for those times.
