A closed orbit of the diagonal flow on unimodular 3-lattices: the Minkowski lattice of a
totally real cubic field, stretched along the three real embeddings by a totally-positive unit.
Lₜ = Λ·diag(μᵢᵗ) returns to Λ at t = 1.

The orbit is closed (period 1); μᵢ = rᵢ² are the squared
real conjugates of a unit, ∏μᵢ = 1, so the covolume stays 1. Each glowing orb is a lattice point; the
color loops as the flow plays. Origin view puts you at the center looking out; external view orbits the lattice.
