O’Carrigan’s works take the ‘human condition’ and its accompanying existential void and as their subject matter—though they are sometimes tongue in cheek. In Grey Flags, the works focus on the notion of communication: the pillar on which rests our avoidance of isolation. Flags and placards are greyed out, stripping them of any text, identifying colour or symbol: depriving them of their meaning. Isolated figures—wave their flags meaningless flags at nothing. The works imagine the problems resulting when communication is blocked: they trace the tension between the human need to speak to others about hopes and fears, and the difficulty of doing so articulately.
