It swings over the basin of fine sand, and its tip begins to trace. First a line. Then the trajectory widens, curves, draws an ellipse, a star, a spiral. Geometric figures gradually appear, with mathematical precision and unexpected beauty. Change the amplitude, alter the direction, vary the speed — and watch the physics of motion transform into ephemeral art with each oscillation.
