Links, Tangents, Grids and Foam (Olympic Arrays II)

The previous post brought in a wave of traffic (hello!) largely due to the connective clout of City of Sound (thanks Dan). More importantly the ideas I sketched there have been drawn in to various other discussions, including some fascinating anthropological thoughts on sport, the (transhuman) individual and the collective. Interestingly some of the more thoughtful responses came via the newly-enlarged notes field in delicious. Rodcorp wonders if the opening ceremony will come to be seen as "the defining image of peak energy" - I'm not sure; I think the massive deployment of LEDs makes a sort of cake-and-eat-it statement about abundance and the spectacular. In other words, this is "efficient" spectacle. Does anyone have the numbers on the power actually drawn by the whole show? Sevensixfive takes up the "human pixels" as a harbinger of Deleuze's society of control - though for me Deleuze's notion of control as "modulation" resonates more (and almost uncannily) with the architecture:

[T]he different control mechanisms are inseparable variations, forming a system of variable geometry the language of which is numerical (which doesn't necessarily mean binary). Enclosures are molds, distinct castings, but controls are a modulation, like a self-deforming cast that will continuously change from one moment to the other, or like a sieve whose mesh will transmute from point to point.

Which brings us neatly back to the aesthetics and cultural valency of computational architecture. I suggested that the organic multiplicity of the Birds' Nest and the Water Cube can be thought of as a post-industrial grid, where the regularity or (via Deleuze) control has in a sense moved inwards, to the level of the generative system. What we have is a kind of managed heterogeneity, where each element in the structure can be unique because computation ensures that it all works out the same and guarantees against failure. It's interesting, tangentially, that in the organic "models" for these structures - a nest of twigs, a blob of foam - the morphogenetic forces have more to do with local adaptation (to failure) than any global summation

This reading - managed heterogeneity - seems to work for the Birds' Nest, though on closer inspection the Water Cube is actually a far more literal grid. As Dan Hill points out, its bubbles are based on the Weaire-Phelan structure, a formal solution to an optimisation problem posed by Kelvin: how to divide space into equal sized volumes, with minimal surface area. One by-product of this minimal surface quality is that the structure resembles a lattice of bubbles - but these are highly idealised bubbles: uniform in volume. Moreover the Weaire-Phelan structure is spatially regular - as outlined here, "two irregular pentagonal dodecahedra (12-sided) and six tetrakaidecahedra (14-sided) form a translation unit with a lattice periodicity which is simple cubic." In other words, it's a cubic grid, though the modular unit is built from two different, irregular solids. Although I'd never noticed it before, the regularity of the grid is clearly visible on the building's surface - notice the recurring pattern in the image above (by Chris Bosse, via archidose).

As this Science News article reports, the design masks the grid structure of the foam by slicing it obliquely: "by cutting at an angle of about 111 degrees, [Carfrae] found a pattern that looked entirely natural. In fact, the pattern actually repeated in ways that were very hard for the eye to detect." At the same time, "That repetition was key, because it meant the building would be far easier to construct." So this is a formal grid, that's trying to "look natural" - and as such it's exactly like the terracotta warriors, whose "simulacrum of diversity" is constructed from permutations of mass-produced modules (see City of Sound quoting Craig Clunes, earlier in this conversation).

I'm not sure what this amounts to - perhaps it simply shows how metaphors (foam) and categories (post-industrial) are never quite what they seem, especially as they meet the pragmatics of real architecture and engineering. The Water Cube's hypermodern image rests on an aesthetic of "natural" variety and multiplicity - and after a week of the Games it's unquestionable that these structures are fundamentally machines for producing images (televisually, and literally, in the case of the Cube's illumination). But that aesthetic rests in turn on the modern industrial logics of the grid: modularity and regularity.

Have a look at David Rokeby's
"Cloud" 2007... its behaviours emerge from phasing between an array of panels suspended in a large atrium.
