Spectral Harmonographs

This Python + Pygame program draws the trace of 4 decaying sine waves, 2 per axis, with rainbow colours. It generates a sequence of random harmonographs.

A harmonograph is a mechanical device typically seen in science museums, that has two …

Extensible Harmonograph

Often seen in science museums, the harmonograph is a device that combines wave motions (e.g. from some pendulums) to move a pen resting on a sheet of paper. These movements result in attractive patterns. This device can be simulated easily …

Black & White Harmonographs

Black & White Harmonographs. Because colour gets boring after a while…

Harmonographs are those devices often seen in science museums, that consist of a pen connected to a number of pendulums, suspended over a sheet of paper on a board, …

Online 3D Harmonograph

Online 3D Harmonograph

This is an online 3d harmonograph version of those harmonograph devices often seen in science museums – except that instead of drawing pretty harmonic patterns on paper, here we plot them in 3D-space! Glowscript code and my …

Spectral Harmonographs

Not fractals – but still, pretty math pictures… These were created with the following Python program (MIT license; download from GitHub):

You may need to install python and/or pygame, e.g. on Ubuntu/Debian style linuxes:

sudo apt-get install pygame
