Fourier Epicycles FAQ
How do I set Fourier Epicycles as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Fourier Epicycles 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 Fourier Epicycles as a live wallpaper?

Is Fourier Epicycles free?
Fourier Epicycles 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 Fourier Epicycles a video loop?
No. Fourier Epicycles 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 Fourier Epicycles 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 Fourier Epicycles costs next to nothing in everyday use.
