Lattice with X-unit, Merry X-mas! Schoen's GW surface, Ningboballs, magnets tutorial @EdoTimmermans

The structure has the same topology as Schoen's GW surface. The GW surface comes in a graphite sheet hexagonal structure or in a wurtzite structure (hence the name), in this case the wurtzite structure is approached. When a 60 degree Bonnet rotation is performed on the unit (that looks like an X from 3 sides), rotating the top section, then you get a unit that forms Schwarz' P surface.

$Sierpinski octahedron & more The Sierpinski ocgtahedron is a 3D fractal. I remember seeing Sierpinski cubes and tetrahedra made with magnets, but not the octahedron. My build only is the second iteration, with smaller octahedra a third iteration should be possible to make. The other builds in this video, made with the same octahedra: a dodecahedron and a tetrahedron.$
