A product of the industrial revolution - the chalkboard represents a technology where written information could be broadcast to a large audience. As a metaphor, the chalkboard becomes the physical embodiment of the blank slate - an empty foundation to be filled with reason. It could be used, erased, and overwritten with new information. The vitality of those facts was short lived, as the audience was responsible for transposing and archiving the material. What was once public became secret when erased.
The chalkboard was once considered to be distortion free, and a photograph was once considered a transparent window onto the world. By photographing chalkboards with film, the syntax of both technologies becomes apparent. The temporary schematics drawn on these boards to emphasize abstract ideas are now embedded in the slate. A useful chalkboard has no history; a used chalkboard is history. What was once empty is now full of information.
