Two moons share almost the same orbit and, instead of colliding, trade places each time they meet, shown side by side as seen from space and in a turning frame where their paths become horseshoes.

In the app you can adjust the colours, view, speed and trail length. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Orbit Swap FAQ
How do I set Orbit Swap as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Orbit Swap in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.
Can I use Orbit Swap as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Orbit Swap plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Orbit Swap free?
Orbit Swap is included in SCRNSVRS Unlimited. It's free for your first 7 days; after that Unlimited is $1.99/month or $9.99/year (€1.99/month or €9.99/year) for every screensaver, including new ones. It can also come up in Free this month, when 25 premium screensavers are free for everyone.
Is Orbit Swap a video loop?
No. Orbit Swap is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.
Will Orbit Swap slow down my Mac or drain the battery?
No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Orbit Swap costs next to nothing in everyday use.
Which Macs does Orbit Swap run on?
Orbit Swap needs macOS Tahoe 26 or later.
