Hey! First off, newbie here. Used GIMP for a long time and just got my hands on Inkscape. It's amazing and I love it. Anyway, I've seen some ways to do "brushes" in Inkscape and some splatter brushes to use, but I was wondering if there was any 'random selection' feature or plugin or something. For instance, I have, let's say, seven "splatter" brushes similar in size but different in shape, and I want to have them cycle randomly in order to achieve that awesome 'paint-splatter-on-canvas' look.
I have a piece
here that's kind of what I'm looking for. But, it'd be much easier if the brushes automatically (and hopefully randomly, but that isn't really required) cycled out, instead of me having to manually get a new brush every time. Hopefully that makes enough sense...
So, does anything like that exist? If not, how should I go about bringing it into existence?

Thanks!
