I would say that one of the major ways his work changed was that it provided further expansion to Close's understanding of photorrealism. Close had to reconfigure the way in which his art was created in the wake of "The Event." In attempting to conceive of a new manner in which work was to be displayed, the grid- like approach actually provided a new manner in which his photorrealist style could be conceived. I think that this becomes one of the most interesting elements regarding his work after "The Event." The process by which he had to reconstruct his work was more "digital," in a way. He was able to use the grid setting to pixel-ate his work, something that was not as pronounced before his illness. In this manner, Close was able to replicate or recreate the same photorrealist effect, although in a different way. From an artistic point of view, this is unique because it reflects Close's fundamental desire to change the way in which art is both constructed and viewed. Close's work had always challenged conventions, and this was one more way to challenge his own challenges of artistic conventions. I think that another way in which Close's work changed was that it forced him to recognize that while he could not devote a certain level of focus in one manner, he was able to channel it into another, proving again the fluid nature of both art and the process that gives birth to it.
