Computing peripheral maker Logitech must be getting tired of the vacant stares its new Cube is getting at the Consumer Electronics Show in Las Vegas, as the company has issued a video explaining how the unique interface device works.

In the video, Logitech brand manager Todd Walker shows how the device, which is about the size of a nine-volt battery, can be used as a mouse – with a tap on the top to click and a slide down the top to scroll – and also as a presentation pointer, with a tap to go forward and a tap with the device held upside down to go backward.

Check out the video below, and post your comments under that – is it a nifty piece of kit, or just a silly gimmick?
