Imaginary Cube

Imagine an object that has square silhouettes in three orthogonal directions.
How many shapes can you guess?
A cube is an answer, of course. A regular tetrahedron also has this property.
We call such an object an
Imaginary Cube
because it let you imagine a cube determined by the three silhouettes.
In my investigation on imaginary cubes, I encountered imaginary cubes
with beautiful properties, and I designed puzzles and created some sculptures.
Please enjoy!
