adobe illustrator - How do I scatter icons all over a background randomly?

I've been wondering this a time now but I just saw a background like this on dribbble. I want to have multiple icons scattered across a background with random position and random rotation using Illustrator could someone possibly point me into the right direction?

To make a pattern main steps.

1. Make your bunch of icons which you want to be repeated.


2. Go object > pattern > make


3. make modifications that you want (overlap, tile type etc.)


4. under file name click done


5. you can find it in swatches panel.
