CMU has a lecture series entitled, "The Last Lecture." It is supposed to be your chance to talk about things that matter deeply to you. For Randy, it really may be his last lecture.
I first watched his 10 minute reprise of his lecture as a email forward...
After watching it, I wanted to see more. Here is the full video (76 min) from his original talk, "Really Achieving Your Childhood Dreams..."
The second video is more sincere and drawn out and I recommend viewing it.
Also, I was surprised to see a co-worker in the second video, Tommy Burnette. Tommy got a nice shout out from Randy for following his dreams to work on Star Wars.
I've seen Randy's work at SIGGRAPH's Emerging Technologies. He's worked on a VR project called "Alice."
