Changes every time the page reloads, or if you click here: Oops. Do you have Javascript disabled maybe?
You can add this random link thingy to your page by adding <script src="http://tilde.town/~nick/js/link.js"></script> to your page and then adding a <span id="link"></span> where you want the link. Email me at nick@tilde.town (works only from the server itself) if it doesn't work.
