Hey!
I'm looking for some simple to understand and impressive examples of fun things teens might want to do with PHP.
Ideally interactive things their friends might want to try on a local intranet server.
PHP mixes with HTML in a really fun way, and I remember doing some neat tricks with it... but I'm very rusty.
What are the cutest things you've ever seen done with PHP?
(We will get to the issues with security later. Fun first.)
