Probably unnecessary, but possibly useful--and odd no matter the case...Thanko loves to come up with new takes on USB-powered everything (gold brick USB hub, case in point), and this time, it's a butt cooler. Yes, as in your rear end. It works like an air hockey table, blowing cool air out. If you're not lucky enough to have a Aeron chair that keeps you cool and you prefer to not be in the hot seat, check it out.
