Blue Concentric Spiral Illusion - Abstract Optical Art #3301657 (License: Personal Use)

The image features precisely rendered concentric circles in vivid electric blue, separated by bold black rings that intensify the perception of depth. As the rings narrow toward the center, they produce a strong tunneling effect reminiscent of op art and perceptual psychology demonstrations. The clean vector-like rendering ensures sharpness at any scale.
