Wow! The dripping/drying effect is really cool! Reminds me of a concept I wanted to try a while ago - a machine that produces watercolours, so like a "printer" that uses a camera and actual watercolour paints, brushes etc to recreate the scene as best it can. The idea was for it to be live on the scene, as opposed to looking at an image file or whatever, so it would be seeing the scene evolve like a human painter would. And there would be some element of art to how you wrote the software, making tradeoffs/guesses about how the paint will behave and how the colours will mix, plus maybe some kind of ML inspired approach to how best to identify and capture the most salient aspects of the scene and to produce something that conveys a particular style.
