It would be nice to make it as a sculpture, using magnetic levitation, but it seems to be physically impossible (“Earnshaw’s theorem proves conclusively that it is not possible to levitate stably using only static, macroscopic, paramagnetic fields. The forces acting on any paramagnetic object in any combinations of gravitational, electrostatic, and magnetostatic fields will make the object’s position, at best, unstable along at least one axis, and it can be unstable equilibrium along all axes…” Wiki)
