Twins

Both pictures come from one drawing. A landscape is laid out — hills or a plain with a pond, a tree holding one edge of the frame or just a bough leaning in, someone standing in the grass, something up in the sky — and then it is painted twice, the second time with a handful of quiet edits. Something changes color, grows, shrinks, shuffles sideways, turns around, becomes something else, or leaves entirely. The hour and the weather are rolled too, so a round might arrive at dusk, under cloud, by moonlight, or in falling snow. Nothing here is a photograph and nothing is stored: every scene is invented in your browser the moment you ask for it, so you will never see the same one twice.

Click either picture where you think a difference is. You have as long as you like; the only thing counted against you is a wrong guess. More differences also means a busier scene to hunt through, and each setting keeps its own best score in this browser. Give me one hands over a difference you have not found, which finishes the round but takes it out of the running for a best score.
