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.

Also available at Shapeways in a a variety of fine plastics. This design generated an interesting halfway point that's on Shapeways too.  It has a different symmetry group from the final cut, for obscure reasons having to do with coloring.
