A thickening matrix

The photographic detail in google maps streetview has always freakwented me out slightly, but today I noticed something I had not seen before. The streetview images capture not only physical space, but also movement through time. A good example can be seen if you search "smithfield and 6th avenue pittsburgh" on google maps, and drop down into streetview about halfway along the block to the left on 6th avenue. Aim Eastward. Start clicking your way down the street, and observe people and cars moving across the streets, moving forward with each new frame. Move in the opposite direction to see things moving backwards through time.
