	Randomly Shuffle Liquid Array
	Author: Stephen Ginn at cremadesignstudio.com
	Credits: Random Number function from @131_studio
	
	Usage: {%- include 'random' with 'a,b,c,d,e' -%}

	This snippet does the following:
	1. Creates a new array with the provided string
	2. Calculate X amount to loop, based on array size times 10.
	3. Loop X number to generate random indexes using fancy date and math logic.
	4. Strip out duplicate keys and echo new array. That's why we looped 10x the array size.

{%- assign array = random | split: ',' -%}
{%- assign loops = array.size | times: 10 -%}

{%- capture indexes -%}
	{%- for i in (1..loops) -%}{{ "now" | date: "%N" | modulo: array.size }},{%- endfor -%}
{%- endcapture -%}

{%- assign indexes = indexes | split: ',' | uniq -%}

{%- for a in indexes -%}{% assign b = a | plus: 0 %}{{ array[b] }}{% unless forloop.last %},{% endunless %}{%- endfor -%}

Appears to not really be random. It's random as of the build time & then it's cached. SCSS & JavaScript remain the easier ways to randomize.
