Abstract: A three-dimensional platform comprising a tessellated surface of pieces, each piece comprising a top and sides. The pieces comprise a fixed square piece having at least two opposing sides orientated acutely relative to the top to define a fixed square retention surface. The remaining surfaces orientate substantially perpendicular relative to the top. There is a mobile square piece having at least two opposing sides orientated obtusely relative to the top to define a mobile square retention surface. The remaining surfaces are oriented substantially perpendicular relative to the top. A mobile triangular piece having all sides orientated obtusely relative to the top. The fixed square retention surface indexes only with either the mobile square retention surface or the triangular piece surface to effect retention of the pieces to define the three-dimensional platform.

Abstract: A toy construction system comprising a releasably connectable tendon or tether (“tendon”) to connect to at least two building blocks. The tendon being resiliently deformable and providing a range of motion for each of at least two blocks, relative to each other, in at least two Cartesian axes. The tendon having an engagement, and each block having a corresponding receiving element.

Abstract: A three-dimensional puzzle or puzzle or display platform being substantially spherical and having a substantially tessellated surface defined by substantially square form areas (first playing piece) and substantially triangular form areas (second playing piece), and having at least two parallel planes of demarcation on each of the three Cartesian axes that define the areas of the surface, and wherein the chord length of both form areas and the triangular form areas are substantially similar. The puzzle or game platform may be in conjunction with a levitator.

Abstract: An apparatus useful as an educational device, puzzle or toy of a kind having magnetic interactions between an elongate support and pieces held, or to be held, with or without contact, about said support, wherein a plurality of said pieces collectively form, or can form, a first band of pieces about said support, and another plurality of said pieces form, or can form, a second band of pieces about the support, and wherein at least one piece of each said band has an indicia, said indicia of a piece in one band being able to be indexed to an indicia of a piece of the other band, and wherein at least one of the bands of pieces is able, or will be able, to be rotated about the elongate axis of the support.
