This is a film by Don Hertzfeld. I watched this about a year ago, I think, and I was completely moved by it. I hope you feel for it as much as I did. http://www.4shared.com/video/l1IoNnnu/The_Meaning_of_Life__Don_Hertz.html
Of what I heard, Hertzfeld submits a film to the Ottawa animation film festival every year. Last year, he submitted "Wisdom Teeth," which I had the great grace of having a film I worked on at CSSSA open up for. Perhaps next year, I may be gifted with the opportunity to meet him.
Enjoy the show!
