Randy, you will always be remembered for all the Imagineering, Alice - my new hobby and lot more in human-computer interaction. I will like to quote a part of the message from CMU president which makes you what you are.

"Perhaps the greatest lesson, however, Randy taught us all was how to live, even in the face of great challenges, and how to follow our passion. While Randy's greatest passion was clearly his family, he did not shy from sharing his passion for his work as a professor, for his students, and for Carnegie Mellon.  We will miss Randy, but we will carry the memory of him and all that he did..."

My condolences to his family.
