Underwater research lab with fish swimming past a round porthole

About this scene

A round riveted porthole sits in the middle of a curved green-grey wall, looking out into deep blue water with drifting specks of light and dark rock shapes. Around it hang hand-drawn charts and maps, an old monitor and a run of pipework. On the left, a control desk has a lit screen and a panel of coloured buttons, and on the right an angled lamp shines on a small table with a steaming mug. Shelves on both sides hold radios, boxes and binders.

Small fish swim through the porthole view, appearing and moving between frames, and steam rises from the mug. The interior stays put under its low, yellow light. The round window makes a strong centre point, so a webcam fits neatly to one side of it, for instance over the control desk. It suits science or ocean channels, coding and study streams, or a quiet second monitor. The 10-second clip loops without a jump and has no sound.

Good for

• Coding and study streams
• Ocean or science channel backdrops
• Second monitor ambience
• Night-time desktop wallpaper

Questions

Do fish actually swim past the porthole?

Yes. A few dark fish move through the deep blue water between frames, sometimes one at a time and sometimes in a small group, so the view never looks frozen.

Is this lab scene good for a coding or science stream?

It fits well. The control panel, monitors and charts suggest work in progress, and the calm blue window gives the eye somewhere to rest between tasks.

How dark is the underwater lab?

Fairly dim. The lamp and the control screen are the bright points, and the rest sits in muted green and navy, which suits dark mode setups and night-time viewing.
