Strange that the passing of a stranger would affect me like that. Through his character, Nimoy has been a part of my daily life for ages. For over 20 years, it's been one of my favorite things to sit in front of an old Star Trek TOS episode w/ a guitar and practice. As a matter of fact, I was doing just that last night before I went to bed...
I'm also a big fan of Fringe, in which he played Dr. William Bell. Great role.
Sad, sad news.
