Apparently, I have always loved wabi-sabi without being able to put a name on it.

There is a Scandanavian movie called 'Drifting Clouds' by Finnish filmmaker Aki Kaurismaki. It came to mind for different reasons, not just the drifting clouds/ flowers. This filmmaker is known for not casting pretty actors but average, ordinary, often considered 'ugly' people in his films.
His films - and the people in it - have a certain beauty to them.
There is indeed often beauty to be found in what other people consider the opposite.

Thanks for sharing this info and especially the further reading!
