Material Design Wallpapers

I'm the type of a person that doesn't like changing my wallpaper very often. But very recently, I've found a pretty nice pack of wallpaper that are completely free to download and use. I'm sure you'll find at least one that fits your taste. 
You can view the whole album here and you can download the whole pack here. 
All wallpapers in this pack actually originated from this post by jathak who got them all in one place. These material inspired artworks are extracted from the Google Now app. 
As you might already know, in the Google Now app, the picture at the top of your screen changes according to the time of the day. 
For example, Google takes the following values for dividing the day to four different parts:

Dawn: 6:00 a.m.

Day: 9:00 a.m.

Dusk: 6:00 p.m.

Night: 9:00 p.m.

There are 44 wallpapers in total, so that means 11 cities, for example: San Francisco (images abowe), New York, Austin, Chicago, London, Seattle and others...

I hope you'll find some that you'll like. Cheers!
