This is a little system I've written that allows you to "surf the web on autopilot". Every twenty seconds, a new web page that is linked to from the current page is loaded. This is pretty rough. There's some horrid hacks right now, but what I'd like to do eventually is to just write a CGI to load a page, or maybe a Java applet to do some stuff.
