An innovative design visualisation environment that uses videogame technology and screen based augmented reality to support arts curation is presented. A follow on project, which exploits scale shifts and distributed presence, outlines one approach to extending the exhibition experience. The project is at the schematic design stage, with the emerging idea being miniature mobile galleries referred to as ‘nomad_tech’. These are intended to have a mixed reality presence in the museum and other cultural settings, while been interactively linked to form distributed virtual environments.
