Harmonograph Dreams
A Coloring Book of Pendulum Curves
$14.99Free shipping
Fifty hand-crafted coloring pages generated by the mathematics of coupled pendulums. A harmonograph is a mechanical device from the 1800s that uses swinging weights to draw continuously looping, hypnotic curves. By carefully tuning the mathematical frequencies, damping factors, and phases, we've simulated these physical systems to create perfectly smooth, infinitely complex geometric mandalas for you to color and relax.
