1. An optical device comprising:
an array of lenses; and
a plurality of first and second segments disposed under the array of lenses, the first segments corresponding to portions of a first icon, and the second segments corresponding to portions of a second icon,
wherein at a first viewing angle, the array of lenses presents for viewing the first icon without presenting the second icon for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second icon without presenting the first icon for viewing,
wherein individual ones of the first segments comprise a first surface texture defining the first icon,
wherein individual ones of the second segments comprise a second surface texture defining the second icon, the second surface texture different from the first surface texture.
