If you care to see a demo, I’ve implemented this script at bulltown, set to activate after 90,000 milliseconds (90 seconds) of inactivity. That means no mouse movement, no keys pressed, and no scrolling, so please be prepared to chill (or do anything else you like in other tabs or windows) for 90 seconds after the site loads. Quick and easy to install and customize – I like it! 😎
