#Unix trivia:
The original #BSD daemon was drawn by John Lasseter for Sam Leffler's "Unix System Manager's Manual". (Lasseter & Leffler (previously at CSRG) worked at Lucasfilm, which sold the Graphics Group to Steve Jobs to become Pixar.)
He then drew the version used by McKusick's "The Design and Implementation of the 4.3BSD Operating System" (McKusick still holds the copyright for that daemon). It was used by #FreeBSD until 2005; #NetBSD used the Iwo Jima inspired daemons logo until 2004.
