A courtyard is equipped with plant beds, planters and all sorts of spaces for greenery. It is also wired with automated systems for maintaining and changing the environment and a variety of sensors that can detect both the health of the plants and the presence of people.
This is all tied together in a robotic gardening system that both tracks which plant beds people stop near and cares for them based on the attention given. The ugly plants are allowed to die, to then be replaced by other plants. Over time, a semi-darwinian process results in the most evenly pleasing garden.
These allows for an objective community-driven decision making system that ensures that everyone has a vote and that the stakeholders who use the garden most get the most say in the final layout. It also allows for a crowd-sourced tinkerer-approach to selecting the best plants for a landscape. Lastly, it allows for an garden that shifts contents as time shifts the tastes and character of the users of the space.
