Absolut sound art installations
I haven't seen <a href="http://absolut.com/absolutmachines">these sculptures</a> mentioned in the usual places--perhaps because of the corporate sponsorship? Absolut imposing its name on the works' titles does seems overly intrusive.
The NYC piece allows a web-visitor to enter a melody, which it plays and develops into more involves variations. The installation is quite fun. It looks like the artists were greatly inspired by the Animusic "Pipe Dream" computer animation. You might recall that animation, it was passed around the Internet a few years under the claim it was a physical sculpture creating by University of Iowa students using John Deere tractor parts.
Videos of the NYC installation and the "Pipe Dream" animation are posted <a href="http://www.ethanham.com/blog/2008/02/absolut-sound-sculptures.html">on my blog</a>.
