Vintage toys and gadgets form a tree ring silhouette

I(0) = blank matte background.
I(1) = final concentric radial flat‑lay forming silhouette $ SHAPE.

∂I/∂t = Δ(I, $ THEME, $ SHAPE) with constraints: center‑to‑rim chronology, silhouette adherence, soft shadows.

Integration:
t=0.0–0.15: faint silhouette outline and concentric guide rings appear.
t=0.15–0.4: innermost objects (oldest) fade in at the center, heavily worn.
t=0.4–0.7: middle rings populate, wear decreases, shape begins to emerge.
t=0.7–0.9: outermost objects (newest) fill the rim, finalizing the silhouette.
t=0.9–1.0: soft shadows deepen, ring labels appear along a radial line, final polish.

Output I(1) as an 8K concentric tree‑ring masterwork.
