A sound installation, in which visitors can listen to various "soundscape" recorded in Yokohama by shining on a miniature model of the city with flashlights. The location of lights on the miniature are detected by a hacked infrared web-camera and a Max/MSP patch, then sounds recorded in the corresponding area are played.

A Max/MSP external object for Freesound project (http://freesound.iua.upf.edu/). You can search, preview and load any sound samples released under CC License on the web site in Max/MSP programming environment.
