Procedurally generated plain desktop wallpapers

Have an option to generate procedurally generated textures like this:

Repeating patterns are a way to have simple wallpapers that are not distracting. They used to be common.
Some pictures of macos 9 desktops I found on internet:

**I would prefer to generate these wallpapers to make them unique and to prevent perfectly repeating patterns.**

Although very colorful and spectacular images could be generated I propose more subtle patterns, colors etc in order to be able to clearly see the desktop icons.

Something which I would like the algorithm to be capable to produce:

Another use for such an algorithm would be to generate unique textures for the title bars of windows based on the text of the title (in order to make the window appear the same each time it is opened but different window title bars different). For example the texture of a slightly crumpled paper for text areas, brushed aluminum etc.
