random idea - Secret Tree

When the people confess their secrets to the tree, the secrets make the tree grow, the flowers bloom and the fruits bear. In the book “The Giving Tree” by Shel Silverstein and the movie “In the Mood for Love” by director Wong Kar Wai, the main characters confess their secrets to a tree because it never tells their secrets to other people and it always keep them as long as the tree stays alive.
The project “Secret Tree” listens, interprets and stores people’s secrets in its leaves or fruits with a unique format. Afterwards, their secret is stored in the fruit and through a speaker other people will be able to listen to these secrets in a unique and altered format.
