VATNAJÖKULL

The boys met up again in front of Vatnajökull (the sound of) – a piece comprised of a neon sign of a long number.

Wilson asked Byron, 'So, Biro – this isn't just a neon sign, is it?'

'You're right!' Byron replied enthusiastically, 'It's a telephone number. You can call it from anywhere in the world and hear the Vatnajökull Glacier in Iceland dying as it melts… it's a very melancholy sound, and a sorrowful thought, don't you think?'

Wilson considered this for some moments, the silence broken only by a performance of Earth-Moon-Earth (an automated grand piano playing Beethoven's Moonlight Sonata, the data having been transmitted from the Earth to the moon, reflected off the Moon's surface and received back on Earth, the music occasionally interrupted or altered by data-loss).

Then he asked, 'Biro, how do you know so much about all this… stuff?'

'Mostly,' Byron replied, 'I just read the labels!'
