Hello, world! is an interesting take on long- and short-lived data storage media. It consists of a computer, a loudspeaker, 246 metres of copper pipes, a microphone and a codified auditory signal that circulates in a closed (feedback) system. Through the acoustic delay in the pipe system, it is possible to store data. The longer the system of pipes, the greater the time delay, and this means greater memory capacity. With 246 metres of pipes, the delay is approximately 0.8 seconds. This is the equivalent of 1 Kilobit memory capacity.

But there is some instability in the system. If you go up to the sculpture you can hear the sounds (every sign of the ASCII code has its own sine wave frequency thus translating it in an acoustic signal) travelling through the copper piping. But a loud noise in the exhibition space or a vibrational disturbance from passing traffic or low frequency rumble effects the lettering on the screen and the text and "Hello, World!" starts to tremble as the quality of the signal degenerates and recovers.
