1. A method for generating an image describing selective contact, comprising:

  • (a) providing a laminate, the laminate including an outer receiving surface, a luminescent layer, a dielectric layer and a translucent electrode layer, the receiving surface on the laminate separated from the translucent electrode layer by the dielectric layer and the luminescent layer;

    (b) connecting a power source to the translucent electrode layer;

    (c) touching the receiving surface with a contact surface, wherein said touching is effective to selectively couple the power source through the contact surface and across the laminate in a pattern in register with zones of contact between the contact surface and the receiving surface; and

    (d) responsive to said selective coupling, energizing the luminescent layer so as to generate light in said pattern.
