Callaghan's work investigates ideas and conjectures about Utopian philosophy and science fiction. He wants to question and address the limitations of the human condition, revealing the simplicity of how we all travel consciously or unconsciously through the third and fourth dimensions of time and space. These conceptual goals directly reference his concerns with how and where science and the visual experience of art meet.

These are treated in contrasting colours in order to maximize optical dynamism and vibrancy. The geometric structures intertwine, appearing precarious and spontaneous, this dynamic state attempts to question notions of order and chaos.
