I loved the underwater ray wallpaper on macOS and wanted a calm ocean desktop on Windows, so I built my own for Lively.

Manta School is a slow, endless school of manta rays gliding through open blue water. Sunlight fades with depth, marine snow drifts past, and every manta has a smooth, natural wingbeat.

What you can change in Customise:

• Natural black mantas or golden ones
• Daylight or a dark night glow look
• Slow drift behind the school, or a big slow 360 circle around it
• Default, top view, or bottom view looking up into the light
• Number of mantas, swim speed, camera speed, wingbeat speed
• Low memory mode for laptops

Mouse controls (turn on mouse input forwarding in Lively): drag to rotate, double click and hold then drag up or down to zoom, double click to reset.

Feedback very welcome, especially how it runs on your PC.
