While Western porn shows everything, Japanese pornography does not. Instead, pixels or blurred mosaics cover private parts (read more as to why here). Online in Japan, people have noticed they can create a somewhat similar effect with iOS 7, using the interface to make images unintentionally sexy.
If you've downloaded the new iOS, you'll know that it has a "frosted" or "blurred" design motif, which Twitter users in Japan are using to add Japanese porn style mosaics to their backgrounds, covering up the naughty bits.
Here's a sample of images, as well as a male tush before and after shot.
