The company where I am currently contracting has regular lunch gathering where a few people talk about their hobbies in hopes that someone else in the room will find the topic interesting.  Today, I gave a short talk on the construction of my home theater.  The goal of the presentation was to layout the various high-level items that one needed to consider when starting a home theater project.  Overall, I felt that the presentation was well received and I'm putting the slides up here as well.
