FORTUNE — The last time we looked at the site of Apple’s (AAPL) new campus headquarters, bulldozers were still knocking down the Hewlett-Packard (HPQ) buildings that used to occupy the site.
Three months later, excavation has progressed to the point where the shape and dimensions of the main building have begun to emerge. (Click for more photos.)

Thanks to Apple Toolbox for the aerial photos and The Loop‘s Dave Mark for the link.
