More than 15 years ago, I had this idea to autogenerate the header image of my website based on the current time of day, season, location, and a simulated weather pattern that naturally progresses. It fascinated me to have a long-running, realistic-feeling, autonomous system that changes itself without my involvement—like its own little world. I liked the idea to open my own site and being surprised by what I see. “Oh, it’s snowing!”, then seeing the snow melt away some time later, or observe the bleakness of misty autumn days.

Back then, I tinkered with layering PNGs on top of each other to create “random” scenes, but it looked terrible. I can design websites, but I can’t draw nice pictures.

I never ended up doing it because 1) I didn’t miraculously become a good artist, and 2) who cares.

Well, I care. I’m older now, and the fascination is definitely weaker, but I still thought about it every year. When my most favorite time of year starts, I get this itch. And this year, I finally scratched it.

AI made this much easier to solve. Not just for creating the images, but also for simulating the weather progression based on the time of day, the season, and previous days. Everything is now truly unpredictable, there isn’t a single line of code where I can already guess what will happen next.

New scenes get generated four times a day, and I feed the AI with previous days to create a natural progression.

I’m storing all the prompts, images and weather simulations (in a Railway Bucket of course).
