Took a walk around Salford Quays last week, Imperial War Museum, The Lowry, Media City. There is a lot of interesting architecture around there, some of which I would call industrial art. Some of the designs are way beyond pure functionality, like this huge hoist. It is one of four hoists that lift up a bridge. I liked the way rigid angles are combined with sweeping curves and the whole thing pierces the skyline.
Angles and curves pierce the sky at Salford Quays.

Your last sentence says it all – the sweeping curves and rigid lines provide the contrast and tension in this image. I had no idea what it was until I read ‘Hoist’. But actually the image stands on its own as an abstract.
Thanks Andy, your comments are always appreciated.
