Joshua Antolovic
Josh is a designer and artist with work centered on video games and natural systems. After working in architecture for six years, working on performing-arts centers, public libraries, and private residences, he pivoted toward interactive media to explore how ecological thinking can enrich video game worlds. Nature has been the consistent thread throughout his creative practice. His architecture projects always featured light wells with plants. His artwork focuses so intensely on natural subjects that horizon lines rarely appear, as if he's solely examining the ground. Now pursuing his MFA in Design, he continues integrating nature into human experience through technology. He works fluidly across interaction, experience, and new-media design, equally comfortable prototyping mixed-reality installations and programming complex systems. This systems-oriented mindset shapes his approach to video games, which he views as powerful spaces for experimenting with social relationships through the seamless integration of narrative, visuals, audio, and interaction. Josh's current thesis research focuses on developing methods that allow digital natural environments to behave as active agents through emergent systems, creating a methodology for bringing more life to natural environments in games so they can function as actors rather than backdrops. His work contributes to an emerging field examining how digital spaces reflect the complexity of living systems. When not designing, Josh can be found working on video game prototypes, taking his dog to the park, or getting carried away in the garden.
