For an internal presentation at our company, we are trying to compile list of advanced a.k.a. cool things which can be done with PHP. We are calling this "Next Web Presentation" so something which can show power of PHP along with a "cool" way of doing it.

I searched around and also walked through http://www.sitepoint.com/forums/show...-PHP-Resources but couldn't find much.

Can you please list some which we can include in our presentation?
