RESEARCH BACKGROUND 'On Nobby Seymour's Etherium' is an essay included in the catalogue documenting the exhibition 'Etherium: An Exhibition of Framed Space' by architect and mural painter, Nobby Seymour. This exhibition investigated Bachelard's 'Poetics of Space', expressed through a series of sculptural models. Van Schaik's essay (pages 15-18), which includes an original ideogram, provides both an overview of the works represented in the catalogue and a broader context in which the artist's explorations sit. RESEARCH CONTRIBUTION This textural work describes the qualities and origins of Seymour's work through discussing intersections between architecture and art, and the ways in which sense making and spatial relationships are constructed through individual interpretation and practice. This work contributes to Van Schaik's ongoing research practice and contribution related to the importance of spatial thinking and intelligence to architectural design. RESEARCH SIGNIFICANCE The publication 'Etherium: An Exhibition of Framed Space' was available in limited print and a copy is held by The National Library in Canberra. A PDF of the catalogue is publically available at Nobby Seymour's website.
