They did the Oddworld theme which is already available.

Dawn (5 AM) <-- sunrise
Midday (10AM) <--fully lit "sakura" scene
Dusk (5PM) <-- sunset,fireflies come out
Night (8PM) <--sun is set, artificial light bathes the flowers
Late Night (11PM) <--- lights out, moonlight emerges
Midnight (12AM) <-- fireflies sleep

woodblock / windchime /shaker sounds for cursors and transitions. Mountain winds and very quiet ambient droning of some insects, with only occasional birdcall here and there

Here's the thread on GAF for anyone interested:

I think this is a very good replacement for the Junebug Bench theme I have on PS3.

This is amazing.

That's a beautiful theme. I really like some of the PS4 themes, they are a really nice touch.
