  • (a) an elongated handle, said handle having a brush end, a back end, and a longitudinal axis extending through said brush end and said back end;

    (b) a first brush head attached at said brush end of said handle;

    (c) a number of nonrigid optic fiber bristles protruding from said first brush head in a direction away from said handle, said optic fiber bristles having a handle end proximal said handle, said handle end of said optic fiber bristles being secured to said brush end of said handle such that said handle end of said optic fiber bristles are relatively immovable relative to said handle in a direction transverse said longitudinal axis, and said optic fiber bristles having a working end opposite said handle end, said working end of said optic fiber bristles not being secured to said handle such that said working end of said optic fiber bristles are relatively bendable in said direction transverse said longitudinal axis when a force is applied to said working end of said bristles, said optic fiber bristles channeling light from said working end to said handle end;

    (d) means for transforming said channeled light into an electrical signal; and
