Square mouse from felt

From under the pen of designer Joe Roth (Joey Roth) came out a very unusual creation. Usually, users of mouse-type manipulators seek to choose a device more comfortably, with smooth corners, rounded, with a smooth but not slipping surface, but the so-called “Felt Mouse” is a mouse that does not fit into the general and familiar concepts of ergonomics and design.

In addition to the shape of the product is unusual and material manufacturing. The mouse is made of natural felt, with a strip of bamboo laminate around the perimeter. The softness and playfulness of the manipulator, as reported, makes the device comfortable for use without the "caricature type of ergonomic". So that the “tail” of the optical mouse did not spoil the appearance, it was probably decided to make it wireless. True, on the background of the mouse design such important trifles as the resolution of the sensor and the range of action are simply not given.

Well, a bold decision with a “brick design” (however, the designer probably did not dare to make the scroll wheel square), which looks undoubtedly original, but ... whether the softness and design of the mouse contribute to the convenience of its location inside the palm, especially in everyday use ?
