Any good CSS3 shadow tutorials, plugins or examples?

I'm joining together a huge list of CSS3 shadows that will include tutorials, plugins, scripts and more. I have discarded all the other search methods and I hav开发者_如何学Goe found some pretty cool things, but still I'm sure that I can find even greater things here, thanks :)...

This is a good one

Maybe this tool is useful: http://www.css3.me/

You can do some nice css3 stuff on an html div with some sliders and options. You can see right away what you are doing. When your done you can generate the source code and use it on your own website.
