I’ve had a link saved to these pictures for quite a while, and of course they’ve been linked from countless sites over the years, but hey, they’re still worth linking to again.
The thing that I’ve noticed about them is the effect of the small thumbnails all together. You click them and in a way some of the mystery is dispelled, as the smaller size allows you to see the overall pattern. They could be microchip designs or supermarket shelves, so I put them together at a couple of sizes below. To see the details there’s an original size one too.
