This sensual tree, built of copper, reacts to the closeness of the audience. When the audience approach, the tree performs an electro-acoustic version of an aria by G. F. Handel with its trembling loud-speaker-leafs. In this aria, Xerxes gives voice to his love for a tree that allows him to seek refuge in its shadow.
Through the stem of the copper-tree, wires lead from the base to brass-leaves that tremble by the sound waves. Two sensors are placed on the stem, and through the computers and circuit cards placed in the root system they transform the movements of the audience to music, wind and light.
