In the app you can adjust the colours, lines and elevation tint, keep one variation or get a new one every time, and choose how often it fades to the next. Nothing moves in between, so it uses almost no energy – one still image, drawn natively on your Mac at full resolution.

Terrain Lines FAQ
How do I set Terrain Lines as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Terrain 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 Terrain Lines as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Terrain Lines plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Terrain Lines free?
Terrain 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 Terrain Lines a video loop?
No. Terrain Lines is drawn on your Mac with Metal at your display's full resolution, then holds still, so it stays sharp on any display size and uses almost no energy. The preview on this page is a capture of the real thing.
Will Terrain 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 Terrain Lines costs next to nothing in everyday use.
Which Macs does Terrain Lines run on?
Terrain Lines needs macOS Tahoe 26 or later.
