Space

Space.
It has an impact on virtually anything. Functionality, emotions are the two main things that come to mind when I think of the artistic element of space. Different kinds of space are needed for different functions. To play soccer you need greater open (negative) space. Emotion is impacted by space as well. In an empty elevator I tend to feel like I'm being pulled outwards while in a crowded elevator I feel pushed inwards. Sitting alone in an open field looking up into the vast endless sky will give you a different feeling than sitting in a lecture filled with people staring at the same useless information scrawled onto a whiteboard by a tired, unpassionate teacher. Space represents emotion and functionality. Looking at a picture of a little girl standing in the middle of an empty street will give you a different idea and emotion of the story behind the photo than of a little girl standing next to who seem to be her parents at a crowded fair.
