Abstract:
1. A spherical puzzle, comprising: a first semi-spherical shell having four triangular panels held by a first plate having a front and a bottom side, the four triangular panels forming an intersecting track having a center cut running perpendicularly along an x and y axis; a second semi-spherical shell having four triangular panels held by a second plate having a front and a bottom side, the four triangular panels forming an intersecting track having a center cut running perpendicularly along an x and y axis, the track on the x axis of the second semi-spherical shell forming a continuous track with the track on the x axis of the first semi-spherical shell and the track on the y axis of the second semi-spherical shell forming a continuous track with the track on the y axis of the first semi-spherical shell; a plurality of sliding tiles placed on the intersecting tracks, the sliding tiles forming a predetermined pattern or design; means for engaging the triangular panels to the first or second plates; means for keeping the sliding tiles on the intersecting tracks; means for engaging the first semi-spherical shell to the second semi-spherical shell; and, means for allowing one semi-spherical shell to rotate about an equatorial axis relative to the other semi-spherical shell.
