Someone did something like this with a torn-apart 5k iMac, mounting the display in a gilded frame and having it cycle through various images of fine art but only when the camera determined that nobody was looking at it.
>A fun (but impractical and frustrating) variant of this feature is to have the image change as soon as the viewer looks away. So you’re looking at a painting, glance away to another room, and look back to find a new painting hanging on the wall.
Also interesting that the iMac doesn't have TrueTone, so he had to do the white-balance matching himself.
