The work of Angus Tarnawsky is something like a study of the aesthetics of the signal — as in what happens on a path between a catalyst and a conveyance (in a gallery setting). Like all good, empiric, paired-down art (Graham, Sandback, Judd, etc.) Tarnawsky demonstrates that simple changes whether of viewer proximity or viewer interference, to simple conditions, cause alterations that are fairly complex. We see the metaphor, and have no problem drawing conclusions as to what happens when the conditions themselves are complex (and not in a gallery setting).
