From left to right: Cupcake (Android 1.5), Froyo (Android 2.2), Eclair (Android 2.0/2.1), Gingerbread (Android 2.3), Ice Cream Sandwich (Android 4.0), Honeycomb (Android 3), Android mascot aka Andy aka Bugdroid aka Astro (Android 1.0), Donut (Android 1.6).

These statues, in front of Building 44 on the Google campus, commemorate each Android release from Cupcake onwards.

Taking a panorama this close-up makes it look like the sculptures are all in a straight line and the building is curved. In fact, it's the other way around: the front of the building is straight, and the statues are in a roughly 90° arc around the viewing point on this path.

Alas, this picture was out of date even before I left Mountain View: a few days later I watched them bring the jellybeans out of the building and into a giant jellybean pot.
