Out Of Space

Upon three walls and the floor, a 3D model is projected.
The projected model represents the space itself, where the projection takes place

The 3D model being projected isn't stable, it moves slowly and mutates.

Outside the building, on a stone wall, a mechanism made of mirrors is placed, the mechanism redirects sunlight from outside into the room at any given time (except at night).
Inside, in the corner of the room, there is another mechanism. built from a mirror mounted on a cooking timer.

The sunlight sent from outside hits the mechanism which transports it slowly across the room. The timer winds itself automatically every 12 and a half minutes, filling the room with a ticking sound
