Fine droplet tracks appear in a dark, misty chamber – long straight streaks, short fat stubs, curling spirals and the odd fork – and slowly fade away.

In the app you can adjust the colours, event rate, magnetic curl and mist. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

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