Wabi-sabi is a Japanese aesthetic that celebrates the imperfection of things.
When applied to bonsai, the viewer is encouraged to watch with their heart instead of their eyes, to understand the beauty of their constant changing.

This expansion for Bonsai contains 5 modules that can be combined together or used separately:

New Shitakusa Tiles that double the score of Goal tiles;
New Goal tiles;
New content for the 5th player;
New type of Zen cards, for even more choices;
