This is an inspirational “must see”:

“With equal parts humor and heart, Carnegie Mellon professor and alumnus Randy Pausch delivered a one-of-a-kind last lecture that moved an overflow crowd at the university – and went on to move audiences around the globe. Randy died July 25 of complications from pancreatic cancer. He was 47. Randy’s family is planning a private burial. A campus memorial service is being planned and details will be announced at a later date.”
