In January 2017, a large wind turbine blade was installed temporarily in a city square as a public
artwork. At first sight, media photographs of the installation appeared to be fakes – the blade
looks like it could not really be part of the scene. Close inspection of the object shows that its
paradoxical visual appearance can be attributed to unconscious assumptions about object shape
and light source direction.
