Diesel Wall - Barcelona '08

The sky above is the only constant factor on any building (façade) for sure, always present, with clouds circling around it, creating a natural atmosphere. Inside the building we have another type of sky: full of wires, ducts, and pipes that give life to the building, forming lines of communication, air condition, power, and electricity. This image is a contrast between natural and artificial sky, a wire/cloud passing by and reflected on the wall of the building.
