Using 'abstract' as an adjective might actually put Karen's image within that category, Alan. Here's a list of definitions, with number five probably having some bearing on Karens image:
1. thought of apart from any particular instances or material objects; not concrete
2. expressing a quality thought of apart from any particular or material object: beauty is an abstract word
3. not easy to understand because of being extremely complex, remote from concrete reality, etc.; abstruse
4. theoretical; not practical or applied
5. designating or of art abstracted from reality, in which designs or forms may be definite and geometric or fluid and amorphous: a generic term that encompasses various nonrealistic contemporary schools
I think a lay person viewing this image without being given any title or explanation could quite likely see it initially as a geometrical abstract. The least it would do is make them try to work out what it is. If the pylon had been photographed upwards from a central position its true nature would have been a lot more apparent but, for me, the offset view is what lends it an abstract quality and makes it a lot more interesting.
I keep getting the urge to infill some of the shapes with primary colours in a Mondrian sort of way
