What would it mean if communication were exact? That, in spite
of the real, material, spaces of message, channel, format, filters,
modulations, mediation, and plain old error, it might be possible
to exclude all noise and see through to some pure space of connection
and transmission. Despite my curiosity, I suspect the result would
be disappointingly dull, or simply redundant. The search for perfect
communication is as pointless as trying to find an audio space not
infected with electromagnetic waves, or a gallery space where only
one work is apprehended at a time. Our communications spaces are
always already determined by the varieties of noise that constitute
their surfaces. In scientific and informatic models there are laws
that repeatedly demonstrate the futility of any attempt to maintain
purity as a static form. Key to these demonstrations is the role
of entropy. Entropy is both a force and a probability measure. This
essay examines shifting roles and definitions of entropy in two
recent digital installations. What I suggest is that an understanding
of the operations and implications of entropy helps us to unpack
operations of noise and materiality in these works. The installations
discussed here use the tools of distributed media at the same time
as they locate themselves within the physical spaces of the art
gallery. Furthermore, a focus on entropy and its role in digital
installation acknowledges that both information theory and aesthetics
are themselves impure and inexact.
