To know your Android A-B-C-s, then please read as follows: cupcake, donut, eclair, froyo, and gingerbread. Those are the version of Android named after desserts, 1.5, 1.6, 2.0/2.1/, 2.2, 2.3 or 3.0, respectively. Some Googlers and a giant truck bring along what can only be described as a giant Gingerbread man to stand next to the FroYo sculpture. Keep in mind every time a figure like this is erected, members of the press (LaptopMemo, somewhat included) are invited to check it out.
The video, available in full 720p HD is down there for you gadget-loving newcomers to look at.
