Snoopy

Snoopy is a bookmarklet for snooping on web pages. It’s intended for use on mobile browsers (such as Mobile Safari on the iPad) where you can’t view-source to poke around under the hood of sites to see how they’re built. You might find it useful for your desktop browser, too.

This is very cool. I’ll need to put this onto my iOS test devices - it’s a lot faster than plugging in and using the remote debugger.
