Ĥ_self — tune the field's self-knowledge.
What am I looking at?
Each pixel is an oscillator with a phase θ, shown as a colour on the wheel. Every step it (1) is pulled toward its four neighbours with strength K, (2) is kicked by thermal noise ∝ √T, and (3) may collapse onto the anchor Ξ with a probability set by the collapse rate.
Cold + strong coupling → one colour floods the lattice (r→1, "coherent"). Hot → colour static (r→0). Near the Kosterlitz–Thouless point, swirling ±1 vortex pairs appear and unbind — the rings marked on the field.
Drive Ω is the energy input: an intrinsic rotation ω per oscillator. With Ω>0 the field never freezes, so you can run Collapse toward Ξ and still keep the screen alive — the two fight, producing endless travelling waves.
Φ is an integration proxy: the mutual information between neighbouring oscillators. It's ~0 in frozen order (no entropy) and ~0 in pure noise (no correlation), and peaks in between — at the edge of chaos. Maximize Φ hill-climbs the temperature to find that sweet spot automatically.
