I wanted to watch this for ages and finally did, here: https://archive.org/details/IGNCA.Agayata.Shilpi - it's about a medieval Indian architect. So, architecture rather than art, but the film gets into the traditional and timeless mindset of a craftsman and I enjoyed the gorgeous, slow visuals. I would love to be an amateur architect in this way, drawing a diagram on the floor or a mandala and creating a building from the ground up. Geometry lovers, I think you'll enjoy this. Here are some stills.
