The CSS Zen Banger
CSSZenBanger is a simple tool for previewing style modifications on an existing web site—mainly intended for web designers who want a quick way to review stylesheet changes without the trouble of setting up a project environment.
This is certainly not a new idea, but I googled in vain for something similar. And while it's pretty easy to make on-the-fly changes with tools like Firebug, sharing the results with others is tricky.
So here it is... if you ever need to test some css fiddles, maybe it can help you too.
