We all know Star Wars has been incredibly influential in more ways than could ever be truly understood or agreed upon. However, this iconographic (which is apparently a few years old) recently showed up on /film and I think it is a very noble attempt at tracing the lineage of some of that influence. It's well organized and really puts into perspective the way so many things are connected.
For instance George Lucus>Star Wars>Industrial Light and Magic>ILM Computer Division>EditDroid>Avid which then crosses over with Pixar>Steve Jobs>Apple>Final Cut Pro (the FCP is my own addition. I extrapolated, you see.) Lots of cool threads to check out.
