The Fidget Drawer
Pendulum Wave
A row of pendulums of slightly different lengths, all released together. They swing in and out of step, making snakes, waves and what looks like chaos, then slowly come back into a perfect line every minute. It is mostly for watching.
How to play
- It starts on its own (in Calm mode, press Play). Pause stops the pendulums exactly where they are; Play carries on from there.
- Speed chooses 0.25, 0.5 or 1 times. Pendulums chooses 10, 15 or 20. Line them up again starts the cycle from a straight line.
- Rainbow bobs gives each pendulum its own colour. View from below looks up at the bobs, which shows the snake patterns clearly.
- In the side view you can drag the row to one side and let go: the further you pull, the wider they swing.
- With sound on, each bob plays a soft note as it passes the middle, so the notes chime together when they line up.
- With the pendulums selected, the keyboard works too: Space plays or pauses, the up and down arrows change speed, R lines them up again and V switches the view.
- Calm mode starts paused, swings half as wide and runs at half speed.
