Computer mouse pad

A mouse pad having a lower surface for resting on a support structure and an upper surface for supporting a mouse having a mouse ball, the upper surface of the mouse pad being formed with grooves that are large enough that dust particles will fall into the grooves and will not adhere to the mouse ball when the mouse is moved over the mouse pad, the grooves being of width substantially smaller than the diameter of the mouse ball and being spaced at a distance substantially greater than the width of the grooves so that the mouse ball rolls smoothly over the mouse pad, and wherein the grooves are at a spacing of about six times their width.
