The new sensory path sounds were unveiled at the open house of the Indianapolis Art Center on Friday 9-11-09.
This is the YouTube video of the Nina Mason Pulliam Sensory Path experience.

As you walk through the Art Center's Nina Mason Pulliam Sensory Path, a dozen infrared sensors detect your passing and each trigger a random playback of a sound from a large library of mp3 files stored on a memory card.
Each MP3 sound file in the library is from 15 to 30 seconds long. The result is a completely random composition played for you as you walk through the sensory path.
Usually the path is silent until you walk through it, but if several people are using it while heading in opposing directions, you will experience sounds already in play as you approach, but they are changed quickly to newer sounds as you pass by each infrared sensor.
