Usage.md

Usage:

• open any website using jQuery.
• in the URL type

    javascript:$('*').each(function() { $(this).css({background: "#"+((1<<24)*Math.random()|0).toString(16)});});

Yes! it's ugly!

Ugly, but fun :)

Just run:

var jq = document.createElement('script');
jq.src = "http://code.jquery.com/jquery-latest.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);

→ profit on every website! 😉
