Well, you'd have to be really bored, but...if you go to Meowmania, you'll find an almost blank screen. Click anywhere on it and a meowing cat head appears. Click again and another cat head appears and...well, you get it. (I'd compare it to counting sheep, but staring at a computer screen tends to keep people awake so...Meowmania isn't really a very good sleep aid). Still, I have to admit that I did this several times.so it did hold some attraction as a time waster (there may be a way to start over, but I couldn't figure it out. I had to click the back button and then the forward button to clear the screen).
