3D capture of bird flight

It's the sculpture-equivalent of Duchamp's Nude Descending a Staircase, No. 2, this sculptural work by Geoffrey Mann. He used long-exposure photography to capture a bird's landing. Then he traced the contours of this bird and used them to sweep a three-dimensional form through. This gave rise to the beautiful shapes you see in these pictures. It would be interesting to also do such studies for the air around the bird, so we get a more embodied insight -complementing the scientific and conceptual- into how air really behaves when manipulated by organic shapes, and how these shapes have evolved for this manipulation.
