Lissajous Harmonograph
Frequency ratios, phase shifts and damping made visible.
What is this?
A drawing machine for Lissajous and harmonograph curves. It turns simple sine waves into loops, knots and slowly fading mechanical-looking drawings.
How it works
The x and y positions are generated by oscillators with adjustable frequencies, phases and damping. Integer ratios create stable closed figures; near-ratios create drifting patterns.
