From Dan Pink's talk at the RSA, animated.  Like Attlassian, and on the topic of autonomy and motivating smart people, we recently started 'Developer Days' where we encourage all engineers to work on any technology related project they choose during the 2 days and then present it to the larger team at the end. Very casual, very fun.  

Unfortunately nobody wanted to pair with me on writing a program in Scala that generates objectiveless meeting agendas and powerpoints filled with 3x3 diagrams.
