Sustained Coincidence

Subsculpture 8
Sustained Coincidence is an interactive installation activated by the spatial relationships of visitors within a gallery. The piece consists of a series of incandescent lightbulbs that light up in reaction to the participants’ positions, in such a way that the shadows cast on the opposing wall are always overlapping. The piece is inspired by the phantasmagorias on the one hand and surveillance and digital analysis on the other.
