I feel like this photo does a great job of emphasizing space and line. Space more in particular, as the lines leave absent areas in which you are able to look through.

I think this is a pretty obvious demonstration of pattern as there is a clear, constant, and exact repetition of these shapes.

The position of which these art pieces are in demonstrates balance.

Principle: Unity
The unity in this photo is represented through the unity in the mouses and keyboards as they are all aligned.
Element: Line
