ABSTRACT:
A support device for a computer mouse (mouse pad) comprises, extending over the lower foil made of foam material, at least one thin, colored liquid layer which is enclosed between two foils welded together along the edge in a liquid-tight manner and is visible through the transparent foil or foils. The liquid occupies the available cavity only incompletely and it spreads out in puddle-like patterns to define void spaces which change continuously due to the actuation of the mouse, thereby providing the mouse pad with an optically interesting appearance.
