Try moving your cursor around in any direction, move it continuously then stop suddenly, and also try clicking you mouse! I laughed a lot when I saw this this website, hahaha... Oh, and in case you don't know Japanese, all of the men will be shouting out the direction they're supposed to go to whenever you move your mouse, like "FRONT FRONT!", "BACK BACK!", "RIGHT RIGHT!", and "LEFT LEFT!" ...not so sure whether they're also saying "DIAGONAL DIAGONAL!", that one I couldn't hear well, hehe...
Edit: after playing around with it more, now I'm quite sure that they said "DIAGONAL", too XD
It may get rather noisy... so if you don't want to wake up your neighbours, do lower down the volume XD
Thanks Nas for sharing this! ^_^
