Hate to break it to these guys: shaking a developing Polaroid is just like tapping the unopened top on a can of something carbonated. It’s just something to do while you wait around for equilibrium (can) or chemical reactions (Polaroid) to occur; these user-actions aren’t actually doing anything.
But, even if we accept the (wrong) notion that shaking a Polaroid picture does something: Why in the name of Christ would one want to implement said delay in the “development” of a photo on an iPhone? It’s beyond reason. It’s like paying to have the iPod app “warm up” for a few minutes when you launch it, complete with some simulated tubes glowing more and more brightly on the screen. Or making the YouTube app disappear slowly into a central dot when you close it and periodically lose vertical hold while you engage in spectation unless you beat the side of the phone a time or two (this app would also need a distant voice screaming not to hit the TV, you’ll break it! after each required series of phone-taps).
Other than that: great product, boys. Positively bully!
