About this tool
A Lissajous figure is the path of a point whose x and y coordinates oscillate at different frequencies; adding exponential damping on each axis produces the decaying harmonograph curves drawn by Victorian pendulum machines. Both are evaluated straight from their parametric equations here, so changing a frequency or a damping factor redraws a mathematically exact curve, and the frequency ratio is shown as a reduced fraction. The trail animates on a canvas with requestAnimationFrame and every export is produced locally — nothing is uploaded and no data leaves your browser.
