How the Windows 7 start up animation evolved

Recently I saw this article on how the Windows 7 start up animation evolved and not to forget, the person behind the Windows 7 start up animation, Rolf Ebeling.

“Having only been with the company for four months and suddenly finding myself working on the first thing millions of people would see when they started up Windows 7 … was a peculiar realization to wake up to each morning,” Ebeling says.
