There are people who wander through google maps looking for spatial and temporal anomalies. I'm not one, but I noticed one that's close to home. If you look at the neighborhood around the New School's new University Center - a cleared building site. Same
for streetview! Zoom in, however, entering their 3-D mode, and it shoots upward (though the image is still more than a year old - 
compare)! Wonder when it'll update to show the now complete skin...
