Here is a photograph of a railway crossing. This is where two sets of track cross over each other. This is a bit unusual as there isn’t a junction in the cross-over. The result is that there the rails have a very pleasing, sharp, geometry. Also, this geometry gives the railway a sort of sparkle, or dazzle.
This is exactly like the optical effects favoured by the Futurist and Vorticist artists at the beginning of the 20C.
Implicit in the low point-of-view is a visual reference to Cassandre’s famous poster.
