Wooden cityscape twists on a knot with infinite streets

2x2 grid, 16:9 do this for 4 famous cities: I(0) = raw wooden knot, unadorned, smooth.
I(1) = fully realized city‑on‑knot sculpture with paradoxical orientation.

∂I/∂t = Δ(I, $ city) where Δ is conditioned on:
- Extracting urban structure of $ city
- Mapping continuously onto Ω
- Enforcing no global up (orientation field with non‑zero winding number)
- Wood material and gallery lighting.

Integration steps:
t=0.0–0.3: Street grid etches itself onto the wooden surface; roads form infinite loops.
t=0.3–0.7: Buildings extrude, but orientation continuously twists along the surface, creating the “point inward, outward, sideways” effect.
t=0.7–0.9: River and landmarks appear, also following the twisting frame.
t=0.9–1.0: Gallery lights switch on, casting complex intersecting shadows inside hollows, final macro photographic tuning.

Output I(1) as a stunning tabletop sculpture image, 1:1, pale wood, ultra‑detailed.
