Pernambuco Python User Group - History of the Local Community 2007-2011

I've created this video using the visualization tool Gource and Python Scripts for extract the history of the all discussion list at Google Groups of the Local community of python users at Pernambuco. This video tells since 2007 until 2011 all the main events that happened in the community and how they affected the growing in number of members in the discussion list.

Each node represents a new user that joined the list. And each user represents the specific event that triggered these joinings.

This video was presented at the X Local meeting of Pernambuco Python User Group at Livraria Cultura , Recife - Pernambuco.

PS: Gource is a tool designed for Control Version history, so I adapted it for showing the history of the group.
PS2: The soundtrack is Paint it, Black - Rolling Stones
