Wall Splatter

If you are one of those who like to frequently change the background of their desktop, you might appreciate Wall Splatter and the many wallpapers it packs.

Straightforward Unsplash client

To get this app on your PC, you first need to access Microsoft Store, so the latest Windows flavor needs to be running on your device.
It needs to be mentioned that the pics provided by this utility come from Unsplash and you can choose the categoriesyou are most interested in, such as nature, people, architecture, interiors, fashion, travel, family, history, animals, bokeh and many more.
A few customization options
Before you start looking for the ideal wallpaper, you can specify the topic you prefer, as well as the picture orientation - landscape, portrait or square.
Once you have found the wallpaper you like best, you have several options: you can download it to your PC as a JPEG file, you can set it as desktop background or you can apply it as your lock screen image.

No automated wallpaper rotation

However, one of the biggest flaws of Wall Splatter is that you cannot schedule it to automatically switch the desktop background according to your criteria. In other words, you need to manually access this application, look for a suitable Unsplash image, then apply it, instead of having this entire process simplified and automated.

To wrap it up

In a nutshell, Wall Splatter can help you add a nice touch to your desktop, assuming you are willing to spend time manually looking for the new wallpaper and applying it.
It does not require any expert skills, nor does it take up a lot of your computer's resources, so you should be able to enjoy its feature-set without any errors or glitches, even if you are not a tech-savvy user.
