"Massaging" optical mouse by Loas

We can totally see the advantages of haptic feedback when it comes to videogames—the RumblePack really does enhance the gaming experience—but for day-to-day computing, do we really want our mouse to shake and vibrate beneath our hand? Well Loas of Japan must see an untapped market of cubical workers who suffer habitual hand cramps, as they will soon be releasing a vibrating mouse with special massage grip to ease your troubles away. For only $20, we might actually be tempted to give this Windows-compatible optical rodent a try; either that, or we're gonna get a bunch of them for our graphic designer friends and have a good laugh when we see their published work come out all squiggly and uneven.
