This sound sculpture is reminiscent of the more well known Cosmic Cubes, but is in the form of a disk. It is the only piece like this in the collection. Reinhold Marxhausen was perhaps most famous for his sound sculptures. After they appeared on NPR and Late Night with David Letterman, he received requests for them from all over the United States. Shake or tap the piece then hold it to your ear. You can hear this piece in the video below.
