the target is not fixed

“He had built a computer program that was slowly but steadily erasing all the MP3 files in one particular music-sharing network; as the files were erased, their lengths altered another program which projected a series of pulsing white rectangles on the floor and played an eery, wave-like soundtrack. Patrick rubbed his eyes and stood up, and together they stared down into the terrifying, beautiful void he had constructed, a wolf-like face of nihilistic perfection.”

Skyline is a data sonification and visualization environment which presents a slowed down picture of activity on a file-sharing network. A remote computer running a spider program found and gathered MP3 compressed audio files using a word association algorithm. The data from each file was compressed into a series of average values which were then used to modulate small frequency differences between eight sine waves diffused on four speakers in the corners of a room. The resulting difference tones were reinforced by controlled variation in a minimal video projection on the floor of the room.
