In the app you can adjust the paper, ink, draw speed, lines, bumps and bump height. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Geodesic Lines FAQ
How do I set Geodesic Lines as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Geodesic Lines 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 Geodesic Lines as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Geodesic Lines plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Geodesic Lines free?
Geodesic Lines 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 Geodesic Lines a video loop?
No. Geodesic Lines 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 Geodesic Lines 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 Geodesic Lines costs next to nothing in everyday use.
Which Macs does Geodesic Lines run on?
Geodesic Lines needs macOS Tahoe 26 or later.
