I like these ice records by artist Katie Paterson. She recorded sounds from a number of melting Icelandic glaciers, then pressed the recordings into ice to make single use records. Besides being a neat statement about how the glaciers are disappearing, it’s also some cool technology. Who knew that you could make records out of water? Needless to say, the records melted during playback, however she did make a recording as they played. [via neatorama]
