We continue our time travel arc with a discussion of our favorite time machines and modes of time travel. And we run down the week in geek, including the world’s first robot-run marathon, a custom fan-built Megatron tank, details about the inside of the Star Wars AT-AT, sad news about Star Trek IV cinematographer Don Peterman, and Simon Pegg’s one-word analysis of the new Star Trek movie sequel script. If you haven’t yet RSVP’d for this year’s 3rd Annual GWC International Meetup, get on it! It’s approaching fast.
