Evolution of the Android interface in pictures

It's amazing how much and sometimes radically changed the look of Android. This system is very strong, has changed almost beyond recognition in just a couple of years some.
I remember watching her appearance and development since then, as soon as the first read on the Web, Google started the development, tracking the emergence of the earliest versions of the screenshots, and then acquired the HTC Hero, which Android was not like that, he had seen earlier in the Scrin. Installed the firmware to the drain to see and feel what it is - a naked Android really is.

Since then, the appearance has changed very dramatically and continues to change and improve. And changed the menu and their structure, fonts, icons, animations, the appearance of all the elements. There are even a guideline for registration application to match the overall style of the system.
It is interesting to recall what it was Android from version to version?
