THREE-DIMENSIONAL MAGNETIC BLOCK SYSTEM AND METHOD

Disclosed are methods and systems of blocks with magnets, magnetically-attractive non-magnetic elements, and magnetic detectors. The methods and systems facilitate user attachment and detachment of the blocks to each other and detection of which face of which block is attached to which face of which other block, and in what orientation. The blocks can be comprised of multiple regular convex polyhedra, such as tetrahedrons, cubes, octahedra, dodecahedra, or icosahedra. The faces of the blocks could be equilateral triangles, squares, or regular pentagons. The methods and systems can further comprise a selection pen and system software configured to render the blocks and their attachment to each other on a display.
