Reykjavik, capital of Iceland, is planning to relocate its Vatnsmyri airfield and redevelop it as a science park. So far, so clear. French architect Vincent Callebaut has come up with a solution called the ‘Neuronal Alien’. There are lots of rather swirly, organic images so, seeking elucidation, Astragal turned to Callebaut’s explanatory text. ‘The Neuronal Alien extends itself between the fauna and the local flora to rebuild a new multi-biotope,’ Callebaut writes. ‘This will develop itself as a metabolic and porous organism, able to regenerate itself by the absorption of the surrounding landscape. A new tangled and interwoven fragment of the territory tends to let itself penetrate deep down in its alveolar excrescences. It is a habitable body in reactive process to a new urban sociability! Through this three-dimensional network of cellular crevices come to mix together the urban, informative, biochemical, physiological, spatial and climatic flows that hang thus to the surrounding quarters and to the life of this ice island.’ Hmmm.
