Dark trunks against a deep green dusk, with fireflies drifting between them. One of the quietest scenes here.

Why fireflies
Movement You Do Not Have to Watch
Small and Unpredictable
Each firefly fades in, drifts a short distance and fades out again on its own timing. Nothing crosses the screen, so there is no motion large enough to catch your eye while you are reading something else.
The Colour Matters
The green glow sits in a narrow band of the spectrum, which keeps the scene dark overall. A brighter or whiter light would make the same movement far more distracting.
Where It Suits
Evening work, a bedroom clock, a quiet waiting area, or a classroom during silent reading.
Depth Without Images
The trunks are drawn at different widths and opacities, which reads as distance. It is a cheap trick and it works: three flat layers look like a wood.
Under the hood
How This Scene Is Built
The trees are flat silhouettes at varying widths and opacities, which is enough to read as depth without any images being involved. The fireflies are small glowing dots on independent timings.
If you want the scene completely still, the pause button holds the fireflies where they are. The page also stops animating on its own when your system asks for reduced motion.
Answers
Forest Background Questions
Is the motion gentle enough for a bedroom?
It is the slowest scene on the site along with Aurora. If you want it completely still, the motion toggle pauses everything and leaves the clock running.
Why are the trees only silhouettes?
Detail would compete with the clock. Silhouettes give the scene its shape while keeping your attention where it belongs.
