This is cheaper than a replacement clear backplate for your iPhone. It’s iPhone 5 wallpapers made from pictures of the device’s insides.
It’s pretty neat, and the insides of the iPhone 5 are very, very nicely-arranged. Of course the battery makes up most of the inside. Just take a look.
iFixit has posted two images of the handset. The first (above) is true-to-scale. This means that it is sized to look like you’re actually looking into your iPhone. The second (available at their site) is zoomed out a bit, so that you can see all the inside components.
