Trainbot (via) “Trainbot watches a piece of train track, detects passing trains, and stitches together images of them”—check out the site itself too, which shows beautifully stitched panoramas of trains that have recently passed near Jo M’s apartment. Found via the best Hacker News thread I’ve seen in years, “Ask HN: Most interesting tech you built for just yourself?”.

IF by DeepFloyd Lab (via) New image generation AI model, financially backed by StabilityAI but based on the Google Imagen paper. Claims to be much better at following complex prompts, including being able to generate text! I tried the Colab notebook with “a photograph of raccoon in the woods holding a sign that says ’I will eat your trash’” and it didn’t quite get the text right, see via link for the result.
