Ha, this is great. I hooked up an old photo frame to OpenAI's DALL-E image generator, which is told to make an image based on the current weather data right now. It updates every few hours.
Not my project and I only know it because a friend starred it. Guessing I would say you could run it with sth much less powerful as it just calls the openai based online service linked. Just thought the look is kind of nice.
This is what it's showing right now: https://ibb.co/8K5jZ3B
