joeypc is a JavaScript/jQuery framework for web site entropy from Dan McKeown.
joeypc.js can help you style your web sites with random colors and more. Try out the examples on the joeypc home page.
jQuery is required to be loaded before joeypc is loaded in the web page. See the API page for an example of how to set it up.
joeypc started out as a JS library for the Ryukyu front-end framework.
