The factory/gallery scene places Duchamp himself in a factory which contains his Large Glass and his infamous Mona Lisa with/without facial hair. The image serves to question the mass - production of Art and/or the industrial factory as an art-piece. Other issues of Corporate Art collecting and machinery as art are intentionally implied.
The stereo image is an altered stereo photograph taken by Man Ray of Duchamp's studio. The addition of a record warehouse into the background and a 3-D computer model of Duchamps Chocolate grinder from The Large Glass, both relate to the central element of the original photograph: "Rotory Glass Plates (Precision Optics)". Many of Duchamp's explorations used mechanical rotation to give an illusion of three - dimensional space.
