Ariel Screensaver
As I have mentioned before I went desktopless a few years ago and switched to a desktop replacement grade laptop with a dock. I love screensavers and lock screens so two things I have on every computer in my environment is the City Art Search app from the Microsoft store and the Ariel Screensaver from github which is a clone of the Apple TV Ariel footage screensaver and actually streams the video directly from Apple.
A couple of honorable mentions are the BSOD Screensaver from Sysinternals, And the Flux which is also a clone of another apple screensaver Drift.
As always So long and Thanks for all the fish!
