Hands od the clock stend still if the sorounding environment is quitet. When the sound appears the hands move quicker the louder the environmental sound is.
Technique: a microphone detects sounds in the clock environment and sends data to the software (a pach in Pure Data). Software - throue the MIDI interface - controls the electromotor that moves the hands of the clock. I also used some screws and pice of a adhesive tape. Project was made in the frame of the workshop and exhibition Reality Log/Environmental Scan, led by Stefan Doepner/F18 Institute.
