In his recent works, Thomas Heidtmann examines forms and expressions of exploration, collaboration, and communication. He is fascinated by space technologies, mirrors, and questions of visibility and observation.

He combines traditional aesthetics, materials, and techniques with new technologies such as 3D-printing to create installations and objects that are often interactive and engaging. Interactions vary from the more obvious to arcane. He builds ephemeral solutions for site-specific requirements, as well as autonomous pieces.

His current quest, the long-term project PLACE IN ORBIT*, involves the collection and comparison of material for satellite-inspired interactive objects communicating with each other and the visitor in an exhibition setup, using light, sound, sensors, projections, and augmented reality. In the frame of this project, he founded the Space Art Hackathon SPARTH to seek for innovative ways of collaboration.
