Every mountain path of up and down steps that never dips below the ground, drawn one by one on top of each other into a glowing range – five of them, then fourteen, forty-two and on through the Catalan numbers.

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

Dyck Paths FAQ

How do I set Dyck Paths as my screensaver on a Mac?

Install SCRNSVRS free from the Mac App Store, select Dyck Paths 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 Dyck Paths as a live wallpaper?

Yes. Click Set as Wallpaper in SCRNSVRS and Dyck Paths plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.

Is Dyck Paths free?

Dyck Paths 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 Dyck Paths a video loop?

No. Dyck Paths 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 Dyck Paths 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 Dyck Paths costs next to nothing in everyday use.

Which Macs does Dyck Paths run on?
