Been wanting this for a while (and was kinda sick of my The Matrix background).
So I adapted the "Bigstar" background from the Fansite kit.
Simply cloning the background didn't work too well because the interface is taller than most screens (1080x1920). And simply block-replicating the background left nasty lines that would be a pain in the
cojones to smooth away. So I just sampled the background colors and rebuilt the background from scratch. Then applied a nice radial gradient. From there I transplanted the star and
voila!

I don't have another camera readily available, but it looks QUITE swanky (especially since the S4 does a little lens-flare when bringing up the lock screen and positions NICELY along the bottom of the star).
Also, a quick mod of the black and white Paragon City Seal.
