This Splatoon 3DS Theme Is Everything
Japan-only for now, but it's probably perfect in every way.
Now that Splatoon is out for the public, you can pick up a special 3DS theme based on the game for your perusing pleasure. It's absolutely gorgeous and colorful, with the Inkling Boy and Inkling Girl decorating the top screen and vivid coloring punctuating it all. What's more, it plays that darned catchy song you hear in the waiting room for a match (and the Nintendo eShop right now, if you've been paying attention.)
The games themselves are denoted with adorable little flags, and they change as you scroll through the theme. You've also got a healthy amount of squid ink punctuating the file folders, where you can organize all of your software and other widgets into one area.
Of course, this is only for Japanese 3DS owners right now, but given the massive Splatoon marketing push in the West and other areas, we might very well see an official release here as well. This might well be one of the best themes out there. It could be just as fun as actually sitting down and playing some Splatoon, too. Well, probably not. But it's pretty close!
