Screensavers
Open-source screensavers for Mac, from aerial video footage to clocks and generative animation, installed alongside the built-in ones.
A screensaver runs when your Mac has been idle for a while and is chosen in System Settings next to the ones macOS includes. Third-party screensavers are installed as small bundles and usually offer their own options for colours, speed or content.
The screensavers here vary in style: some show clocks, one plays aerial video footage, and another draws generative patterns. Consider whether a screensaver downloads video and how much storage that takes, and check that it supports your version of macOS.
