    Imaginary Cube Puzzle 3H=6T (by Musep)

    Imagine a three dimensional object which has square projections in three orthogonal directions, as the figure shows. A cube has this property, but it is not the only answer and there are plenty of examples like a regular tetrahedron and a cuboctahedron. Note that a regular tetrahedron looks square from each of its edges, because a tetrahedron is obtained by selecting every other vertices of a cube.

    From an object with this property, one can imagine a cube which has the same three square projections. Therefore, we call such an object an Imaginary Cube ( I-cube in short). I have been studying about Imaginary Cubes and found many interesting objects, in particular when it has a fractal structure. In order to convey this mathematical surprize, I have made some mathematical sculptures.

    Please enjoy them.
