This week we're joined with the artists behind "Open Air". A visual experience set to the 2013 album "Open" by Australian cult band The Necks. It is also a form of creative earth imaging; it combines timelapse Landsat satellite imagery of Australia, with motion-controlled aerial photography of the paintings and processes of Australian painter Emma Walker. Together, these two vastly different forms of aerial earth imaging combine to produce a complex picture of a changing planet.
