Peeling away the interface in an iOS app (opens in new tab)

I love the internet for little things like this. The author proposes a way to achieve the page turn-effect in the Square app, and the one of the actual Square devs sees it and responds directly to explain how it was _really_ done :-) The internet... connecting people for nearly 40 years.

Square's implementation is so drop dead simple: page curl away a transparent view. I would've over complicated it like the author did with screen captures.
