An exercise for the reader:First, we present Fracture. You tap the iPhone to "crack" the screen and then the apps all explode, triggering the rest of the apps to explode in rapid succession. Next, we find SkyFart. You press a little man and he farts. Then you press him again and he farts and again and flies into space. Then you press him again and he farts and flies. Then you press him again...So which app was accepted by the App store with open and which one was rejected?The logical thing to say, based on the common understanding that the expression of gas and fecal matter as a mode of transport is considered by some to be offensive, is that SkyFart would be rejected out of hand. This is not true.
