Create a dual-orientation optical illusion portrait. When viewed in normal upright position (0° orientation), the image must clearly reveal a young woman’s left-facing side profile. When the image is rotated 180 degrees (phone flipped upside down), the same composition must reveal an elderly woman’s side profile. Both identities must share the exact same contour structure and occupy identical spatial boundaries. No separate drawings, no split screen, no overlay. The transformation must occur purely through contour reinterpretation and structural ambiguity. Design the contour so that: The young woman’s chin becomes the elderly woman’s nose when rotated. The young woman’s ear becomes the elderly woman’s eye socket. The young woman’s neckline becomes the elderly woman’s mouth and chin structure. Apply a Moiré interference surface using ultra-thin radial or dual-frequency line patterns across the entire composition. The interference pattern must enhance depth without breaking the dual-orientation illusion. Strict monochrome palette. Black background (#000000) with white or light gray line structures only. No color. No gradients except those created by line density. No blur. No texture noise. Ultra-precise vector alignment. High contrast. Clean silhouette edges. 8K ultra-high resolution. Aspect ratio 4:5. The illusion must be readable in both orientations.
创作一幅双向光学错觉肖像。 当以正常直立姿态（0° 方向）观看时，图像必须清晰地展现一位年轻女性的左侧面轮廓。 当图像旋转 180 度（手机倒置）时，相同的构图必须展现一位老年女性的侧面轮廓。 两个身份必须共享完全相同的轮廓结构，并占据相同的空间边界。不允许有单独的绘画、分屏或叠加。这种转变必须纯粹通过轮廓的重新诠释和结构模糊性来实现。 设计轮廓时需满足： 年轻女性的下巴在旋转后变成老年女性的鼻子。 年轻女性的耳朵变成老年女性的眼窝。 年轻女性的颈线变成老年女性的嘴巴和下巴结构。 在整个构图上应用莫尔干涉表面，使用超细的径向或双频线条图案。干涉图案必须增强深度，同时不破坏双向错觉。 严格的单色调色板。黑色背景（#000000），仅使用白色或浅灰色线条结构。无色彩。除线条密度产生的渐变外，无其他渐变。无模糊。无纹理噪点。 超精确矢量对齐。高对比度。清晰的剪影边缘。8K 超高分辨率。宽高比 4:5。 该错觉在两种方向下都必须清晰可辨。
