McGinn's practice is a process of excavating the layers of language within aesthetic values and architectural tradition of interiors, and re-layering the contemporary, historical and erotic allegories of these elements. Like baking a cake with the leftovers of another cake, they use mould making and produce casts into object-based outcomes that employ replication, repetition and mimicry. By treating text and image as one and the same, they intuitively aggravate the symbolic malleability of media, re-coding vernacular forms and blurring conventional definitions; the literal and the visual become queer companions in this process. They like to refer to this blended approach as a form of “perverting”; reclaiming a space for informal artistic practice to have a dark sense of humour and strange playfulness. They produce sculpture, installations, interventions, texts and performances as outcomes yet practice a continuity of change within these works, never quite finishing anything and always leaving open ends gaping.
