Something fun that I just ran across .... a “Random Stripe Generator”
http://www.biscuitsandjam.com/stripe_maker.php
Per link:
“I wrote this script to generate random stripe patterns for sweaters, scarves, blankets, etc. It’ll give you an idea of what the finished object will look like, but it still leaves some unpredictability to the stripe pattern. Try it out by entering your colors and desired stripe widths below.”
If you have limited amounts of certain colors, there is also a ‘weighted Random Stripe Generator’ link at the bottom of the post.

The above link was part of a post by Crochet Kim for her ‘Weatherghan’ pattern, which is a temperature blanket:
