Rei Vilo prepared a video illustrating the evolution of Energia over the years. The first commit was late March 2012. The video was generated using Gource, recorded by QuickTime and then processed with iMovie.

Software projects are displayed by Gource as an animated tree with the root directory of the project at its center. Directories appear as branches with files as leaves. Developers can be seen working on the tree at the times they contributed to the project.
