The AOSP (Android open source project) is pretty big to say the least and if you ever wondered what it would look like put together with ever update, commit and release than now you can. A amazing video displaying visually the whole thing, below is the YouTube description to detail it.
This is a visualization of development in AOSP (Android Open Source Project – http://source.android.com) from The Beginning (March 2009) to Ice Cream Sandwich (November 2011).
The graph represents the source tree. Non-leaf nodes are directories and leaf nodes are files where their colour represents the type of file. Files appear as they are modified and disappear if they are not touched for 2.5 seconds.
In other words, each "blast" from a user is a commit. These commits come from both Googlers and contributors. The data was taken from stitching together the logs of all the many AOSP projects. It does not include the external/* and prebuilt/* projects which are dependencies of Android.
Using an open source software called Gource, it simply places the root directory of a project at the centre and then displays each sub-directory as a branch and every file as a leaf. Pretty amazing stuff and it’s imagery is amazing. Sit back and take in the great visuals that is the whole AOSP.
