Pythagoras' garden is a sounding arbor with a structure assembled in the shape of the original proof of the theorem named after him, with a right-angled triangle in the center of three square structures. The structures are made from re-claimed wood obtained locally. Hanging from the arbor are more than 30 small speakers which have been cast from adobe using fruit and other plant-derived shapes as molds for both the inside and outside of the speakers. Each speaker produces small sounds based on insect and bird rhythms, as well as other natural patterns. Each speaker is completely independent form the others, and all sound is generated in real-time and constantly changing in detail. The piece presents a juxtoposition of the rational thought and planning of human-kind (as represented by the Pythagorean proof) with the rich and ever-changing world of rhythms produced by the non-human biological ecosystems.
