双向光学错觉肖像

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.
