I looked at Ora and thought, two tetrahedra in dual position form a cube. How about two 4D simplices forming a hypercube? (A simplex generalizes the idea of a tetrahedron to other dimensionalities.)
The eight triangular elements of Ora become tetrahedra, and now there are 16 of them. The arms with square cross-sections become hexagonal. The way the arms interlock in 3D gets difficult, so I untangled the form. But I kept the twists in the arms that make a two-color arrangement possible, because you need that.
I'm not sure I did this the easiest way, but I was surprised at how it came out, branching and swirling. It's fierce.
