Optical Illusion Circle Pattern - Vintage Halftone Design #267612 (License: Personal Use)

This monochrome image features tightly spaced concentric circles that transition from solid black at the bottom to fine halftone dots near the top, creating a dynamic visual gradient. The interplay of line density and stippling produces an optical illusion of curvature or rotation, reminiscent of 19th-century scientific illustrations or psychedelic art. Its high-contrast structure makes it versatile for backgrounds, logos, or educational material on perception.

Used in design portfolios, psychology or art education pages, retro-themed websites, or as a texture/background for print and digital media; targets users seeking vintage vector art, optical illusions, or abstract geometric patterns.
