Here comes another crazy combo gadget from Japan, that combines more functions than the average geek would need, the LED Message Mouse.
As well as being a standard USB mouse, it can also display messages with the built in LED display, you can display message up to 12 characters, and it also has a built in fan to keep your hands nice and cool.
If you want one of these LED Message mice they are available for about $21 in Japan.
