Google Earth 4th Dimension Redux

After the release this weekend of some new featured layers, many folks in the news media and the blogosphere have been raving about Google Earth's "new" capability to do the 4th dimension: time. The new layer mentioned is the Rumsey Historical Maps Layer (viewable only if you use the latest Google Earth 4 - download here). The historical maps are pretty cool and everything. But, it's not really a new feature per se (the technique for viewing really large images is the real new feature). You could download historical maps and view them overlayed over the Earth even in the first version of GE (see this 1666 map of London for example).

GE 4 allows anyone to time stamp georeferenced data and play it back with the time slider (which was introduced for GE 4 in September). The time feature in Google Earth 4 is really amazing! Here are some links to some of my favorite applications of GE 4's time capability:
