It's cool to see more libraries appearing for this effect. I think it's really nice on the responsive demo at least. It does beg some questions about using it in non-touch scenarios though. The experience with a mouse isn't the best right now because everything moves. Would be curious about the menu having a close button of its own, in the exact same position that the "Menu" you would have clicked to open it was in.
