Folding Paper

App developers can learn a lot from folding paper:

Toying around with a paper model, on the other hand, lets new gestures reveal themselves organically and stay intuitively related. After all, if your paper model is folded into segments that smoosh down into an accordion-like stack, they probably shouldn’t swipe left and right like Scrabble tiles at the same time. If it doesn’t make sense in physical reality, why should it act that way in your app?
