    A real sky, painted

    The sky behind my contact card is not a picture. It is the real sky over one place, painted live in your browser. Scroll down and one whole day goes by.

  2. 07:36Sunrise

    The sun is computed

    Every frame asks where the sun stands at this exact minute. Astronomy formulas give its height and its direction. So the sun rises when it really rises, not when I say so.

  3. 09:30Morning

    Light makes the colors

    There is no hand-picked gradient. A small model of the air scatters sunlight the way the real sky does. It fills a table of 40 by 24 colors while the browser is idle, and the shader reads from it.

  4. 12:38Midday

    Clouds drawn in pixels

    Every cloud is pixel art. The cells are two pixels wide, in six flat tones, with a hard edge and a lit rim. The wind moves them, and a swipe pushes them along.

  5. 15:10Rain front

    The weather is live

    On the home page your browser asks Open-Meteo for the weather where you are. Cloud, rain, snow and fog then ease in over a few seconds. Here a rain front rolls in and clears, so you can watch it happen.

  6. 17:50Sunset

    The words read the sky

    No text here sits in a box. The page reads the pixels behind each line and picks a light or a dark ink. A soft glow does the rest.

  7. 23:33Night

    The moon, on time

    The moon follows the same kind of math as the sun. Its place matches the JPL Horizons tables within 0.006 degrees. Its face is drawn from a map of the real seas and craters.

  8. 00:40Late night

    Now make it yours

    The sky starts over my home. On the home page, open the sky panel and pick your own place on a night globe. Your place is rounded to about ten kilometers before anything sees it.

  9. Now
