It was discontinued (link), but it gave me new ideas where to look. Thanks!

I think I would like the idea (and at first this my understanding) if you could buy one wallpaper for $1 (or a pack of few for $3) and the 70-90% would go to the artist. Also app would have to limit tracking to just some basic stuff. I know you can get wallpapers free, but supporting something that looks great on your screen would be a nice option.

Of course subscription service for this is mad.

Reminded me The Raid (2012) movie concept - jest imagine these cats going through all these floors.
