an mp3-player-like device, that records and plays back environmental sounds. the idea is that while running or jogging, the device records the environmental sound via a microphone, while simultaneously playing back the recording from the previous running session. potential emerging narrative may arrise when you start having a conversation with yourself by repeating, commenting and answering questions from previous runs. it also reflects upon the notion of listening to music while running. this device replaces thumping rhythms of contemporary by the rhythm of your feet. it is interesting to see what the effect might be? does this device create an individual narrative? does it affect the runner? or her performance? is there a training positive or negative effect?
