Pendulum wave

JavaZ wave pendulum with 50 Perlin balls.

Seems like magic, but it’s physics: the harmonic motion.

Harmonic waves created by a serie of simple gravity pendulums looked end on.

Drag and drop any pendulum

The wave pendulum consists of a series of pendulum with increasing length. All pieces are first pushed upwards out of their stable point and release sideways. The very first few swings are going in line. Then they start to go back and forth at different rates.

This device shows a hypnotic effect by having a series of pendula with increasing time periods, producing the effect of a wave. The visual effect here is enhanced by a rendering based on perlin noise.

You can fully test the pendulum by manipulating it or simply toggling the gravity.
