OPTICAL ILLUSION

デジタル錯視 — Where perception bends reality. Move your mouse to create moiré interference patterns.

Hermann Grid

ヘルマン格子錯視

Gray dots appear at the intersections of white lines in your peripheral vision, but disappear when you look directly at them. This classic illusion occurs due to lateral inhibition in the retina.

Op Art Patterns

オプアート

Geometric patterns creating illusions of movement, depth, and vibration. Inspired by Bridget Riley and Victor Vasarely.

Concentric Rotation

Bulging Grid

Wave Distortion

Peripheral Drift

周辺ドリフト錯視

These patterns appear to rotate when you're not looking directly at them. The illusion is strongest in peripheral vision. Inspired by Akiyoshi Kitaoka's "Rotating Snakes."

Penrose Triangle

ペンローズの三角形

An impossible object that cannot exist in three-dimensional space, yet appears perfectly valid in two dimensions. Created by Roger Penrose.

Café Wall Illusion

カフェウォール錯視

The horizontal lines appear to be slanted, but they are perfectly parallel. This illusion is created by the offset pattern of alternating tiles.

Parallax Depth

視差深度

Move your mouse to create an illusion of 3D depth through parallax.

DEPTH

Müller-Lyer Illusion

ミュラー・リヤー錯視

The two horizontal lines are exactly the same length, but the one with outward-pointing arrows appears longer than the one with inward-pointing arrows.
