Mice wheel was one of the petty inventions of the greatest physicians of all time, Sir Issac Newton. It harnessed the muscular energy of rats to rotate pulleys which then in turn triggered the mechanisms Newton required to carry out his experiments. In short, they were a very large pool of mechanical energy substantial to carry out the then gear mechanisms. With the advent of electricity this bright invention lost its importance and was replaced by electric pulleys and gears.

USB Mice Wheel can be called as a tribute from the digital age to the 17th century physics genius. Once plugged into the computer, the wheel automatically rotates with each keystroke from the keyboard. The speed of the rotation of the wheel is proportional to the typing speed. Also, the rodent you see there is an artificial one and you need not feed it on your computer desk! Something sort of a ‘restless indicator’ that bosses in IT firms would crave for; yet, an intelligent choice!
