I was surfing the web and like usual one of my cats was lying on the desk in front of the keyboard. I was using the scroll wheel on the muse when she rolled over to the keyboard. Just like that my screen turned to white with a red digital countdown (digital like 10:00, you know) in the center. Don't know what key or key combo she hit. Is this a hidden feature of XP? A "Ester egg" type situation?
