Tellurite Nanocrystal Ostwald Ripening (2D)

This is the 2D counterpart to the 3D tellurite-glass nanocrystal scene: the same mean-field Lifshitz–Slyozov–Wagner ripening law — curvature-driven diffusion carrying material from small crystals to large ones until the small ones vanish — computed independently and read off a flat crystal map and a live size-distribution histogram instead of rendered spheres. A temperature slider controls the Arrhenius-activated diffusion rate, and an initial-size-spread slider (not exposed in the 3D scene) lets you start the population tightly clustered or already scattered in size to see how much that head start matters to how fast the distribution coarsens.
