Bulloch is interested in relegating artistic decision to the logic of the machine. This work consists of six 'pixel boxes' which project, in sequence, readymade colour taken from the 256-colour palette of Apple's Macintosh Operating System 9. Each box contains one red, one blue, and one green florescent tube, which together can produce millions of colours at a time, many more than the human eye is capable of differentiating. The colour sequence follows the rainbow colours: red, orange, yellow, green, blue, indigo, violet. Bulloch first selects these seven individual colours and then, using 'an evenly calculated numerical program', makes their numerical values shift from one to the next colour. 

The pixel boxes are modular cube-shaped lightboxes and a conceptual product developed in collaboration with artist Holger Friese. As the name suggests, these ostensibly function-orientated light emitters are properly understood as sculptural representations of a pixel - the name for a piece of color information which is the basic logical rather than physical unit of a digital image and whose name is a derivation of 'picture element'.
