• disposing each of the plurality of dual-armed phase-shifting nanostructures upon the transparent metasurface substrate having the first permittivity value in an arrangement of pixels and at a length dimension and a phase-shift angle relative to an angle of incoming incident light that matches a determined phase-shift for the pre-selected image for controlling a color and brightness at each of the plurality of sub-pixels for the pre-selected holographic image in the phase-shifting metasurface of the holographic skin;
• and
• operatively coupling the holographic skin with the phase-shifting metasurface to an information handling system chassis with a light source for display of the pre-selected holographic image.
