bits´n people "Real live" objects have attributes that artificial ones don´t: A tree, a leaf from a tree, tell the state they are in. A car engine, or a car, do the same. With a certain experience you can "read" and interprete these signals. They tell you something. Michael and i had the idea to treat our classroom as a blackbox and to document the state of the class as an audible, dynamic and living "sculpure". After a while it should be possible to distinguish if the Internet was working, if the printer was in use or wether there´s a presentation going on, simply by listening to the sounds in the hallway and/or watching the colourplay on the wall.
