几何错视拼贴

一张正方形平面矢量图：一件原创几何错视。构图为紧密的 9×9 同等菱形单元网格，每个单元仅用三档平涂色——骨白、暖驼、深浓咖——其相邻关系让画面读为从高处四分之三角俯视的叠加立方体阵列。视场中段开始，配色方案翻转，同样的单元突然变为自下方仰视的立方体，沿对角线形成不稳定翻转。每个菱形边缘有一道单像素的奶油色细描线。在主图之上偏中心位置，覆一块更小的六边形九单元贴片，将配色切换为冷调暗石蓝、白镴、墨色，使该区域看似退后到暖色场之后，尽管二者位于同一平面。无渐变、无投影、无纹理——只靠每区三档色做功。网格外背景与最浅一档骨色相同。整体居中，四边留出充足的骨白边距。无文字、无签名、无外框。该图应在第一眼读为干净的印刷品，久看奖励以运动错觉。

A square flat-vector graphic of an original geometric optical illusion. The composition is a tight 9x9 grid of identical rhombus cells, each cell shaded with three flat tones — a pale bone, a warm camel, and a deep espresso — arranged so that adjacent cells lock into the impression of stacked cubes seen from a high three-quarter angle. Halfway through the field, the shading scheme inverts so the same cells suddenly read as cubes seen from below, producing an unstable flip across the diagonal. A faint single-pixel cream outline traces each rhombus edge. Overlaid on top, a smaller off-center hexagonal patch of nine cells shifts the palette to a cool muted slate-blue, pewter and ink, creating a region that appears to recede behind the warm field even though it lies on the same flat plane. No gradient, no shadow, no texture — only the three tones per region doing the work. Background outside the grid is the same bone color as the lightest tile. Composition centered, generous margin of bone around all four sides. No text, no signature, no border. The piece is meant to read instantly as a clean print, while rewarding longer staring with the illusion of motion.
