Forrest seeks to explore some of the cultural, technological and environmental influences that shape our reality. He explores information systems such as the brain and computer. He is concerned with discovering and manipulating the tools these systems use to interpret their environments. In an attempt to understand this new information, his work often implements ideas and methodologies from fields such as technology, science, mathematics and philosophy.
The work takes many forms and mediums and is often exhibited as an overall installation. Depending on the line of inquiry, the medium is dictated by the particularities of the project in question. Forrest's practice encompasses computer code, woodworking, light pieces, paint and electronics amongst other mediums. The work tends to infuse a playful yet technical approach to ideas and art making. Within this approach, Forrest blends conflicting elements such as hi-tech/lo-tech, mind/computer and organic/inorganic. He explores individual autonomy within society through a combination of DIY and mass manufacturing techniques. These ideas of the individual within a larger framework extends into his research on organic and man-made autonomous entities.
