I've always had incredible respect for the art of Bansai. The combination of natural beauty and living design combined with the years and decades of patience required to create something truly beautiful. It's inspiring.
(full disclosure: I have successfully killed at least 10 trees in my attempts to create and/or maintain my own Bansai. I have since decided I will hold off on pursing this hobby any further until I am retired)
Artistry. Craftsmanship. Design.
