LightCoder is an audience participatory installation.
the main installation is an interactive light display. the
audience spins the dial on the top of the installation.
the LightCoder will project the light pulse into short
pulses(dot) and long pulses (dash) , which is Morse
Code.
if the audience wants to know what the sequence
means, then he or she can write down the sequences
and combinations of short and long pulses on a
postcard.
one side of the postcard/codebook displays Morse Code as a
reference (codebook) . based on the sequence, the
audience can figure out the secret meanings that they
decided to ask the light coder to display.
all 60 code sequences come from the list of sensitive
words as a result of the Chinese great fire wall.
