1. An interactive electrochemical display assembly comprising:

  • first and second electrode layers interconnected by an ionically conductive pathway and an electronically conductive pathway;

    a graphic image obscured from view by said first electrode layer;

    a plurality of switches having open and closed states;

    said open states of the switches interrupting at least one of said ionically and electronically conductive pathways;

    said closed states of the switches completing portions of at least one of said ionically and electronically conductive pathways; and

    said switches being closable in a pattern that triggers an electrochemical reaction that erodes at least one portion of said first electrode layer and reveals at least one portion of said graphic image.
