One of my most favorite installations is called "Flow" and focuses on evolving images. Objects that are moving in the space are seen clearly because they are stationary, whereas the movement of people is recorded making them blurry. The feeling of movement in contrast to the architecture gives the piece a unique feel. The artwork functions to showcase the beauty of the natural standing monuments. Watching the video at the bottom of the page gives you a better sense of what the installation would look like in reality.
Rokeby has a ton of other interesting works that are along the same lines. So check out some of his other works under the installation tab.
