The USB Butt Cooler
August 19th, 2006 
A** cooler? Hehe, it is another Japanese gadget letting you relax while sitting on your office chair, it is a USB-powered butt cooler. It doubles as a seat cushion and air is blowing up from the onboard fan to cool your bum. Check it out in this Japan site on this gadget.

These are always good on these hot days and long days that you sit around doing nothing at the office all day!
I could probably use one for my sweaty back too.
last time, i use to have one of this but instead of cooling it makes your ass wet when u sit too long. But not sure about this one from Japan
