A great background or wallpaper can start your day off on a good mood. There’s certainly no shortage of places to find something to revitalize your desktop, whether you are into beautiful landscapes, minimalism, abstract illustrations, or eye-catching designs and patterns. With the kind of hours we spend looking at our computer and smartphone screens, why not make them a little prettier?

Throughout the week we'll be sharing some beautiful wallpapers gathered from around the web by members of the TechSpot staff, each day covering a different theme. To kick things off we're starting with geometric and pixel art wallpapers.
