Abstraction

Here are a couple of my abstract shots:

I like the shadows in this image, because they're also diagonal lines and kind of triangular.
Then there are diagonal lines and triangles in the carpet.
 

This is a close-up of a spider web; the threads are kind of delicate, so they don't show the great shapes I was hoping for, but they sort of contrast the circles in the blurry background.

Here's a close up of some wires; they show curved lines through out the image.
