1. An apparatus comprising:

  • a housing formed from a substrate;

    a surface layer of at least one of a metal or a metal alloy applied on top of the substrate;

    an ablation trench in the shape of a graphic and formed into the surface layer without penetrating into the substrate, the ablation trench including surface variations formed by varying a depth of the ablation trench into the surface layer, the surface variations causing different portions of the graphic to exhibit different optical properties based on the depth; and

    at least one coating applied at a uniform thickness over the ablation trench and at least a portion of the surface layer, the uniform thickness causing the surface variations in the ablation trench to be maintained after application of the coating.
