Musk's code never made it into an official game, but in 1984 the source code for "Blastar" was published by a trade publication called PC and Office Technology.
In his new book, "Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future," Bloomberg technology reporter Ashlee Vance published a photo of the page from the magazine which featured the code.
Now, more than 30 years later, Google software engineer Tomas Lloret decided to turn that source code into a playable game after reading Vance's book. Bloomberg Businessweek editor Josh Tyrangiel noticed the game and shared the link to it via Twitter.
While Musk was enthusiastic about "Blastar," it's still very much a primitive game compared to the popular arcade games like "Space Invaders," "Asteroid," and "Galaga," that all employed similar gameplay mechanics. It's a far more impressive feat, however, when you take into account how young Musk was back then.
