Live time-based work (installation, sculpture, performance) may be performed by non-humans - objects, words, lights, smoke etc. This may question the primacy of human agency and invite an audience to recognise and interact with the material and immaterial world. This work may be considered to be part of scenography as an autonomous practice, and is often influenced by the new materialism theory.
This type of work can be produced and installed according to instructions provided by the artist and presented without the artist's presence.
