Well, not really since the ハムスター is fake...but it's still kinda interesting. Plug the wheel into your usb port and as あなた type the ハムスター reacts to the speed of your typing. Type real fast to get the little bugger moving!
Great site with info on various kinds of hamsters, how to keep/feed/take care of them, including Hamsterific University, "the place to go to find out fascinating information on hamsters that あなた might not find anywhere else."
