I've had photos as my desktop background since I made Irvue in 2015. Simply because Unsplash was only about photos back then. Today I noticed something unusual about my background. I even thought: "Did Unsplash start pushing AI to their front pages?" But at the same time I looked at the image and it actually looked nice. I checked it on Unsplash and apparently it's from The Art Institute of Chicago. Subscribed to their page to have more of these paintings on my desktop.
