I saw this in the Windjammers thread, so I thought I should create a new thread to make it aware to all Gaffers.Basically, if you login to live.playstation.com with your PSN account, you can do a bunch of "quests" to unlock free PS4 themes, as well as get in the Beta of Dreadnought, and as well as get the chance to win a Dualshock 4 and the official Wireless Headset (although for these, it's only if you live in the US, and not in the states of New York or Florida).The FAQ says only 65 000 of these themes are available, so you should get to it. It's super easy, all you need to do is click on the links offered, and when it says to watch a trailer, you have to watch it from beginning to end in both fullscreen mode and theater mode (or else it didn't work for me).For the Windjammers theme, you have to share the trailer on your Facebook profile.The theme is pretty sweet! You have nice wave sounds playing in the background.edit: apparently, this might only be for the North American PSN Store. I'm unsure.
