Hey, guys,
I just published the “Ink Background” plugin. Ink Background is a simple plugin that brings a background effect like spilled paints in the background. To start using the plugin is very simple, create the “Ink Background” element on your page the size you want and that’s it, the plugin will be ready to be used.
See instructions and details on the plugin demo page
