You're so funny, Japan. When I said someone should come up with a mouse that addresses the worldwide hyperhidrosis epidemic, I was joking. I didn't mean you should actually make one with a built-in fan.
Aside from the weird fan inside that keeps your hand cool, this Japan-only mouse, sold by the folks at eSupply for approximately $21, also comes with a remote to type in messages that blink to life underneath the vents while you're not using it. Because that's exactly what Japan needs: more blinking lights.
The mouse is pretty small, so it can only support up to 12 characters. Therefore, brevity is key in getting your message across to co-workers. Message recommendations:
You know, for all the "innovation" built into this mouse, they couldn't have sprung for a Bluetooth receiver or at least a wireless dongle? And what about adding a few extra customizable buttons? You gotta think these things through, Japan, don't you want people to take your combination-input-device-and-neon-sign-and-hand-dryer seriously?
