On Projection

Tatlin's Constructivist tower was to be built from industrial materials: iron, glass and steel. In materials, shape, and function, it was envisioned as a towering symbol of modernity. It would have dwarfed the Eiffel Tower in Paris. The tower's main form was a twin helix which spiraled up to 400 m in height, which visitors would be transported around with the aid of various mechanical devices. The main framework would contain three enormous rotating geometric structures. At the base of the structure was a cube which was designed as a venue for lectures, conferences and congress meetings, and would complete a rotation in the span of one year. In the centre of the structure was a cone, housing executive activities and completing a rotation once a month. The topmost one, a cylinder, was to house an information centre, issuing news bulletins and manifestos via telegraph, radio and loudspeaker, and would complete a rotation once a day. There were also plans to install a gigantic open-air screen on the cylinder, and a further projector which would be able to cast messages across the clouds on any overcast day. (Gray 1986)

What does overdetermination mean, as far as neurotic symptoms are concerned? It means that interference will occur between the effects that correspond in a subject to a particular demand and the effects of a postion in relation to the other (here, his counterpart) that he sustains as subject. "That he sustains as subject" means that language allows him to regard himself as the scene-shifter, or even the director of the entire imaginary capture of which he would otherwise be nothing more than the living marionette.
-Lacan, "Direction of treatment and principles of its power"
