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

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