FORTUNE — The video above was posted on Apple’s (AAPL) home page on the first anniversary of Steve Jobs’ death. On Friday, CEO Tim Cook marked the second anniversary with a letter to his employees:

Team-

Tomorrow marks the second anniversary of Steve’s death. I hope everyone will reflect on what he meant to all of us and to the world. Steve was an amazing human being and left the world a better place. I think of him often and find enormous strength in memories of his friendship, vision and leadership. He left behind a company that only he could have built and his spirit will forever be the foundation of Apple. We will continue to honor his memory by dedicating ourselves to the work he loved so much. There is no higher tribute to his memory. I know that he would be proud of all of you.

Best,
