“Camera Lucida is a highly introspective immersive spatial art work creating a fleeting ephemeral materiality by intersecting ultrasound with hyperlight… in essence the creation of a sonic aurora. Domnitch and Gelfand’s piece rejects any possibility to be fixed in space and time, but rather offers up the very definition of an unstable work of art, existing entirely for and within the perceptive realm of the viewer.” – Stephen Kovats, Director of Transmediale 2008
