Signals provide a means to communicate. Networks respond to signals and signals form networks. Studying the legibility of signals allows for a translation of layers of language through time and functon. I began looking at the light signals used to control the passage of the railroad and at the Morse code. These signals can be directional and carry a sense of historical weight. I was interested in looking at this sort of highly intentional, manual signal as a means to engage the body in the production of sign, of a code. The act of waving the lantern over the train track or of tapping out letters to spell words is a re-reading / and a re-writing of the message. In both cases, the signaled message is read by the receiver as necessary text after being contacted and formed through the trasnmitter's hand.
