A grid logic puzzle fills itself in line by line from its row and column clues, marking certain cells and dotting the empty ones, until an abstract symmetric motif stands complete.

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

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