Tim Head’s work focuses on the digital medium’s elusive material
substance and on our evolving relationship to it as a physical entity.
Bypassing its usual role of representing images and texts, the work deals
directly with its basic material elements - the luminous fabric of pixels on a
screen that are capable of displaying over sixteen million RGB colours, and
the hidden calculations of the computer operating at ultra fast speeds that
drive these elements. The medium’s underlying material substance is
exposed, moving it out from its usual confinement in virtual space towards
the same physical space that we ourselves occupy. Computer programs for
the digital projections are written to generate unique events in real time. The
unsettled surfaces of the projections are composed of randomly selected
colours, each occupying a single pixel and filling every pixel on the screen,
and programmed to change or move in particular ways across the screen as
fast as possible.
