Wavy Lab offers numerous possibilities, distributed according to the Style and the Mode .
If it is the first time that you use this plugin, then an overview of all its possibilities is available here. Now, i would like to insist on what's new in version 1.1, i.e:
A great improvement of "displace" and "tiles" modes ("undersampling" fixed).
Normal mode supports up to 4 colours.
