An insulating glass unit having a decorative pattern visible to the unaided eye. The glass unit comprises a pair of glass sheets disposed in a parallel, but spaced apart arrangement, thereby defining a gap between their respective inner surfaces. The glass unit further comprises a frame attached around the periphery of both sheets to form a sealed cavity. A first plurality of dots are disposed within the sealed cavity. Each dot of the first plurality is attached to the inner surface of one of the sheets, and has a height substantially equal to the width of the gap. A second plurality of dots are disposed within the sealed cavity. Each dot of the second plurality is attached to the inner surface of one of the sheets and has a height less than the width of the gap. The dots of the second plurality are arranged so as to form a pattern on the sheet that is visible to the unaided eye.
