"Both natural and urban spaces are...'over-inscribed': everything therein resembles a rough draft, jumbled and self-contradictory. Rather than signs, what one encounters here are directions - multifarious and overlapping instructions. If there is indeed text, inscription or writing to be found here, it is in a context of conventions, intentions and order (in the sense of social order versus disorder). That space signifies is incontestable. But what it signifies is dos and don'ts - and this brings us back to power. (page 142)"
Needless to say, these manifestations of power are what many psychogeographers are interested in in the urban sphere, but this paragraph above also reminds us of how those who are moving in, around and out of the Olympic area (or London in general) will be responding directly to the urban décor placed there to control their behaviour. What the Situationists described as "fixed points and vortexes that strongly discourage entry into or exit from certain zones."
So on that note I'll leave you with a great big phallus - London's newest, which I photographed last autumn while it was still under constructions, The Shard. It is a perfect example of the superego in operation in public space. In my slightly-more-than-amateur analysis it represents: erection (in both the architectural and male sense), power and domination over those below (see De Certeau's opening to 'Walking in the City') and 'the voice of the father' (if you don't try and seduce your mother, or kill me, you can have all this too)!
