Clouds Clock
A bright blue sky with cumulus drifting slowly across it. The only scene here built for a lit room rather than a dark one.

Press F for full screen. Motion pauses automatically if your system asks for reduced motion.
Why a bright one
A Scene for Daylight
Most Ambient Screens Are Dark
Almost every animated background assumes a dim room, which makes them useless on a sunny desk where a dark screen turns into a mirror. This one is light enough to sit comfortably in a bright office.
Slow on Purpose
The clouds take between fifty seconds and two minutes to cross. That is slow enough that you will not catch yourself watching them, which is the point of a background.
Where It Suits
A classroom projector during the day, a reception screen, or a second monitor next to a window.
Reading the Light
The warm patch near the top right sits where a sun would be. It pulses very gently, which gives the sky some depth without turning into an effect.
Under the hood
How This Scene Is Built
Everything on screen is a blurred shape moved by CSS. There is no video to buffer, no image to download and nothing that keeps working the processor once the page has loaded, so it is safe to leave running all day on a spare monitor.
If you want it still, the pause button freezes the drift and leaves the sky in place. The page also stops the animation on its own if your operating system is set to reduce motion.
Answers
Clouds Background Questions
Is this heavy on the processor?
No. It is a handful of blurred shapes moving with CSS transforms, which the graphics card handles. There is no video, no canvas and no image to download.
Can I stop the motion?
Yes. The motion toggle pauses every animation while leaving the clock running, and the scene also respects your system's reduce-motion setting automatically.
