Watch One Line Turn From a Circle Into a Square

BEHIND THE WORK

Can one continuous 3D curve be two different shapes?

From above, every point satisfies x² + y² = R², so the projection is a perfect circle. From the side, the same points satisfy max(|x|, |z|) = R, producing a square. The line is drawn once, then the completed curve rotates 90 degrees to reveal both shadows.
