Enlichenment was the thesis project of Anna Snyder. The component of the project that I helped with was an interactive sound sculpture. I was responsible for the wireless transmission between the structure and the speakers. More information about the project can be found on her website.
The source code can be found here.
Below is a video of the sound sculpture in action.
The sculpture and the receiving computer each has an Arduino Uno equipped with an XBee to communicate wirelessly with the other.
The sending Arduino uses a capacative sensor to generate a number based on someone's physical connection to the lichen in the sculpture. The generated number is then sent to the receiving Arduino, where a sound is generated in Processing.
Anna did the capacitance sensing and the sound generation, and I helped her bring the two together wirelessly.
