I've seen this and it's inspiring. If you google Randy Pausch you can find the actual Last Lecture. It's about 1 and a half hours long, but worth the watch if you have time.
Holy smokes. That was intense. And incredibly, incredibly eye opening and inspiring. It's too bad that some of the greatest people ever to live seem to die so young and prematurely. At least Randy had the chance to spread such a great message before he has to go.
