Windchimes
Details
"During retreats Thay (Thich Nhat Hanh) encouraged participants to give calm, bright-eyed attention to each daily activity, whether eating a meal, drawing a Buddha, or just walking quietly, aware of the contact between our foot and the earth which supports it. In order to encourage this kind of mindfulness, a 'bell master' sounded a large bell regularly, and everyone stopped their activity, breathed three times, and recited silently, 'Listen, listen, this wonderful sound brings me back to my true self.' 'A bell is a bodhisattva,' Thay said, 'It helps us to wake up.'" (Peter Levitt, 1988)
Windchimes are in their natural state a musical instrument, a percussion instrument, but when augmented with sensors, windchimes become a minimal interface to controlling sound and creating electronic music. A tangible interface to sound performance. Interfaces that are transparent and invisible to the user and that illicit a sense of surprise when used.
