Hacking into the Lego-Frame
Here’s a hidden detail that’s as meaningless as it is interesting. At the start of Iron Man, we see Tony collaborating with Ho Yinsen to come up with the Mark I suit while seeking refuge in the laboratory cave in Afghanistan. The Ten Rings terrorists are just about to break into the cave, so the pair have to work quickly.

For a brief second, we get a good look at the code running on the computer in the background. For most people, it’s a bunch of gibberish, but for that one guy who paused the movie to take a look at the programming language, they concluded it was the exact same program for upgrading the firmware of the Lego Mindstorms RCX controller.
