Imagine an iPhone case which can hold not only the iPhone 5, but your keys, your cash, and your credit cards. Imagine that this case also comes with a built-in mirror and a telescopic pen. Finally, picture this case as a svelte beauty, a case worthy of the iPhone 5 it contains.
Sound impossible? That’s because it is. The case does hold everything in the list, but it’s as ugly as sin. If you were to take the branches of an ugly tree, fashion them into a giant tumble-dryer barrel and spin an iPhone case inside it – forever – then you’d end up with something a lot like the Cavity Case.
