LabPendulum

This is an interactive experimental application that uses the swing of a pendulum to generate trajectory patterns. Users can set pendulum parameters on a canvas, causing lines to extend with the pendulum's swing, forming patterns of different rhythms and shapes.

You can start with a simple pendulum, adjusting its length, angle, and speed to observe how the trajectory gradually evolves from short lines and arcs into complete shapes. Alternatively, you can explore double pendulums, superimposing periodic variations in two directions to generate richer cyclical lines and symmetrical patterns.
