Five large, freestanding LED panels fill the spaces of the Serpentine. Despite their technological nature, they look like temporary plaster walls and give the rooms a stripped appearance. Images scroll onscreen at high speed. In the darkened exhibition space, they have peculiar light and colors, cold and clear tones.

It will spread to the gardens, the streets, the tube. It comes from a large mural on the wall of the main room, a version of timekeeper (1999).
