1. A novelty item capable of producing variable axis colour mixing, said novelty item comprising:

  • a sphere, spheroid or polyhedron capable of spinning freely and randomly upon many axes of spin when spun on a generally planar surface, the whole exterior surface of said sphere, spheroid or polyhedron being divided into a plurality of generally equally sized and generally equally shaped coloured areas, said axes including both neutral and non-neutral axes, a neutral axis being an axis passing through the center of said sphere, spheroid or polyhedron and through a point on the surface of said sphere, spheroid or polyhedron which is a function point of a triadic colour combination, a triadic colour combination being a set of three of said coloured areas having colours selected from points located at equal spacings around a 2D colour wheel;

    said coloured areas being coloured according to a 2D to 3D colour mapping scheme wherein no two adjacent one of said coloured areas are of the same colour and the colour of each one of said coloured areas is selected such that any two of said coloured areas which are respectively coloured with colours which are at a maximum distance from each other on the 2D colour wheel with respect to any other colour on the 2D colour wheel are also at a maximum distance, measured across the exterior surface of said sphere, spheroid or polyhedron, from each other with respect to any other of said coloured areas on said sphere, spheroid or polyhedron;

    said mapping scheme providing an inherent infinite plurality of non-neutral and an inherent finite plurality of neutral axes of spin of said sphere, spheroid or polyhedron;

    whereby when said sphere, spheroid or polyhedron is randomly spun on any one of said infinite plurality of non-neutral axes a clean mix of colours near the poles and a strobing effect of colours at the equator is presented to an observer, the detailed colour composition of which varies as the axis of spin varies;

    said sphere, spheroid or polyhedron when randomly spun on one of said finite number of neutral axes presenting to an observer an overall even, neutral tone;

    said sphere, spheroid or polyhedron spinning on a planar surface continually and randomly varying its axis of spin so that said sphere, spheroid or polyhedron spins successively upon a multiplicity of the infinite plurality of non-neutral axes interspersed with the occasional spin on ones of said finite number of neutral axes.
