<p>A maze formed of two conductors (210, 211) bracketing the maze path, is traversed by a conductive wand (121) controlled by the operator. To change the difficulty of traversing the path the distance between the conductors may be varied, the size of the wand tip may be varied, or the user may be required to view the path indirectly by looking at a minor. In the latter most instance a cover (112) is positioned to selectively block direct viewing of the path. The cover may be opaque, or it may be made of a polarized material and the maze path selectively illuminated by correct polarized or cross polarized light to make the cover selectively transparent or opaque. An audible alarm and/or digital counter (205) may be provided in the wand circuit to indicate contact with the path defining conductors. Interchangeable simulated environment layout boards (108) may be provided about the path. </p> |
