uber graphics on residential development

A graphic mash-up that makes some of my few attempts (one on migration patterns, another showing the growth of the City of Pittsburgh) at dynamic graphics seem childish, here is a graphic that shows the growth of residential property across the entire United States. You have to check this out:

That is just the view of Pittsburgh. But you can literally zoom into any part of the country and it then shows over time the pattern of development at the parcel level over the last century. It says it is using the date of construction at the parcel level to generate this. I would parse it a bit and say it may not capture very well successive developments that happen on the same parcel, or early development.... but that would not take away from the overall project which really is pretty impressive.
