Optical Liquid Mouse

Are you bored of your boring mouse? Do you need something to keep you awake at work or school? If so then you need one of these Optical Liquid Mice. So whats so special about these mice?
Well the official page says that apart from having an animal bob up n down at you inside the mouse, "you do not need to install any software on your computer - just attach the USB and you are ready to use the mouse."
I say "......."
Each of these mice costs a laughable 1,480 yen.
On a related note, any folks here who prefer a touch pen or a roller over a mouse?
