The iPhone is already poised to become the new big platform for portable gaming, squarely taking on the Nintendo DS, which is currently the king of the mountain. Which is why this handmade iPhone case is so great: it's a Game Boy, the original Nintendo handheld console that started it all.
Yes, you'll be able to smile at the irony of keeping your iPhone in a Game Boy every time you take a call, and you'll also have a downright-adorable protective case at the same time. And for only $15, there's really no downside that I can see. Awesome.
