With the North Devon Biosphere project much in mind, I have just been up to London for the Data Landscapes symposium at Arts Catalyst. The most intriguing work on show was Most Blue Skies by Lise Autogena and Joshua Portway, a sisyphean project to try and capture the most blue sky in the world from satellite data and then to bring that into the gallery. Joshua, the programmer in the duo, talked about how when working this closely with such large amounts of data the data itself takes on its own character and quality, quite separate from what it is meant to be depicting. It seems to me that the hardest thing to do in this technological world it to walk the line between abstraction/data and reality/senses. Most Blue Skies does this brilliantly for me; but I am still not sure exactly what the blue actually depicts, perhaps the colour of the data itself?
