wired ran a piece about Lauren O'Neill's airport art, called "Holding Pattern." rumbling through google earth, she cropped interesting runway designs, focusing these highly detailed studies of airport runway patterns. easy to see why madrid is her favorite: the geometric patterns are quite stunning,
especially when compared to some of the mishmash designs of others, like wellington, nz, which is still cool, but haphazard, really.
anyway, check out her tumbler here: http://holding-pattern.tumblr.com/
