/Terra Chorus is a digital work combining 3D modelling, real-time systems and physical interaction to create a responsive environment in which the viewer becomes the author of what they see. Rock forms, modelled and transformed into point clouds, exist within a virtual space where colour, rotation, scale and particle spread are all mapped to a MIDI controller. Sound and music become instruments of control: the rocks pulse in time with beats, disperse into particles under intensity, and reconstitute themselves in the hands of whoever is present.                        

The choice of material is deliberate. Rock is geological record, a history compressed over millennia into form. By translating these material archives into data that can be animated, scattered and reshaped in real time, the work asks what it means to have agency over the way something is remembered. To hold the controller is to decide how the archive moves, how it breaks apart, how it reforms. The viewer is not an observer but a curator, positioned as the one who chooses how history cycles, shifts and survives.

In this way the work reaches beyond its technical system toward something more fundamental: the question of who controls an archive, and what that control means. The rock does not resist, it responds, and in that responsiveness, it opens a space to ask whose hands those decisions are usually in, and what changes when they are placed in yours.
