Sure, you can build an elaborate-but-bogus box like The
Big Red Button (of Doom) and get some props from your crew. But for real hardcore cred, try building a fully
functional replica of NASA's 1964 prototype for the Apollo Guidance Computer. John Pultorak, a Lockheed Martin software
engineer, did it, and it took him four years. Now he's sharing his project files and guaranteeing that anyone willing
to make the effort can do it in less time, and come up with a better version as well. We're tempted, but what we really
want is the rocket that goes with it (but all kidding aside, you rock, John).
