2X2...iPad Stand?

Admit it, you glanced at this image and thought it was a 2x2 slope huh? I'm not ashamed to admit my first thought when I came across it was "hmm, what set came with that printed slope?" Of course my next reaction was "HOLY CRAP!" I might just have to build one of these genius MOCs by nobu_tary for my own iPad mini. In the mean time, which set did have this slope?
