Wall used computer technology to create this picture. It is made of hundreds of individual transparencies, taken over a period of months, and placed together in a digital montage.

'I've been able to experiment with a new range of subjects or types of picture that weren't really possible for me before. This technology has made available the picturing of possible worlds, parallel or imaginary universes...I have always considered my work to be a mimesis of the effects of cinema and of painting (at least traditional painting), and so the fictional, formal and poetic part of it has always been very important.' - Jeff Wall
