Black light is the highest level of spiritual achievement in Sufi mysticism: it describes the infinite darkness of the sky (rather than the finite darkness at the bottom of a well); it is the colour of the negation of the negative. This installation interprets "black light" literally, making the vernacular neon colours glow in a version of patterned light that sits on the surface of wooden limbs (in opposition to the light emanating from within the copper lamps).
