A clean, precise, and visually striking version of the classic Jastrow Illusion, redesigned for modern 3D printing. This timeless optical trick demonstrates how two identical curved pieces can appear dramatically different in size—right before your eyes.
🎩 What This Model Does
The Jastrow Illusion is a powerful demonstration of how our brains interpret shape, curve, and perspective. When the two pieces are placed one above the other, the top piece looks noticeably longer. Swap their positions, and the effect reverses instantly. It’s simple, baffling, and endlessly repeatable.
