Sony Computer Entertainment just released a new free PS4 dynamic theme on the PlayStation Store.
The theme, which is dedicated to PlayStation Now, can be found here (or by going to Settings -> Themes -> Find in PlayStation Store directly on your PS4), and weighs 17.9 Mb. It also includes an animated background and custom music.
To sweeten the deal even further, all those who will download the demo before January 31st, will be entered in a contest to win one year of subscription to the service. You can find the official rules of the contest here, but you can access the page only if you live in North America. Only North American residents are eligible, anyway.
You can check out two screenshots above and below.
