If the last photo was in one corner, this is the view through 180 degrees.

I'm a big fan of Bridget Riley; particularly her early black and white 60's stuff; as my mother dsays of it - "if it doesn't hurt your eyes, it's not Bridget Riley". Which is kind of what I'm looking for criss crossing, jarring angles, light and shade.

This photo works like that for me. And no; I have no idea what it's supposed to be or do. And it's not obtuse enough to be modern sculpture. Is it? (Discuss.)
