They will remind you a bit of the backgrounds used for Material Design, so if you like that type of composition, wallgen is the tool you are looking for ...
Depending on the arguments or options you use for the wallgen command, will generate images for wallpapers of one kind or another, with shape-based patterns, randomly filled surfaces, image-based patterns, etc. Well, once you know what it is and what it can do, the first thing you should do is install it in your distribution in this simple way and that it works for any distro:

La wallgen syntax is simple:

The available options being –help or -h that allows to obtain help information about a command that it precedes. The available commands are:
- pic: use an image instead of a gradient.
- poly: generate a background with polygons using a gradient.

- slants - generates image with multi-colored lines
With each of these commands, multiple labels can be used to designate shapes, colors, patterns, etc. For example, here you go various samples how to use it:
