Twelve new PS4 themes have been released on the North American PlayStation store, including one for free. You can check them out below.

Interestingly, a free PlayStation Now Dynamic Theme was already released a while ago. This one appears to have the same graphics, but a different music. It's quite good, with a nice animation.

I'll let you judge on the quality of some of the other themes, mostly out of mercy. There's one thing I have to warn you about, though: If there's any dynamic element in the Powers theme, besides the name, I didn't see it after purchasing it. It doesn't even have any music.

You can see screenshots of the themes in the gallery below.
