The present invention describes an apparatus comprising an optical array generating a distribution of partial coherence of light energy and an aperture to select a subset of said distribution of partial coherence. The MCs include a first MC configured to execute a first loop iteration, and a second MC configured to execute a second loop iteration. The nebulizer includes a movable gas diverter that diverts pressurized gas across a liquid outlet. A voltage is applied to the electrode assembly, which causes a metal film to selectively form on portions of the conductive surface that are positioned beneath an electrode exhibiting a positive polarity and, thus, negatively charged. The bright ornamental feature is alternatively provided as: of self-luminescent characteristic; or alternatively, as an electrically-powerable incandescent bulb powerable from a chemical storage-battery that is rearwardly removably attachable to the walking shoe environment.
