Now that you have a new icon pack to consider, wouldn’t it be great if someone gave you a wallpaper pack to go with it? Oh, well, would you look at that. Here’s one!
This pack is called Plastexo, and it is indeed hot. It’s very minimal and flat, with some Material Design influence, but you get quite a wide range of options in it that aren’t just MD abstracts. There are 110 or so 3200×2560 wallpapers that include a variety of landscapes, Lollipop classics, and even some ultra minimal hex art.
The pack is entirely free, includes Muzei support, and is one of the most well-designed apps I have used in a while.
