Kanizsa Shapes FAQ
How do I set Kanizsa Shapes as my screensaver on a Mac?

Is Kanizsa Shapes a video loop?
No. Kanizsa Shapes 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 Kanizsa Shapes 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 Kanizsa Shapes costs next to nothing in everyday use.
