Decoupage Black & White Spiral Optical Illusion 薄葉紙

This bold black‑and‑white spiral design creates a powerful optical illusion, pulling the viewer’s eye straight into its center with dramatic motion and depth. The alternating curved bands tighten as they swirl inward, giving the impression of a vortex or tunnel effect. Crisp contrast, smooth curvature, and perfect symmetry make this design ideal for modern art projects, digital backgrounds, decoupage, or any creative work that needs a striking, high‑impact visual.
