On one level, I'm interested in how the space dictates the effect visually - how the composition of a given work changes depending on the nature of each wall. But I'm also trying to emphasize less tangible elements: the amount of time it takes to walk the gallery's perimeter; how one's physical distance affects his or her sense of the overall composition; how the size of the space creates a sense of visual rhythm. It's really a matter of seeing how much structure is necessary to impose for those things to become apparent.
