A crazy British engineer named Iain Sharp decided to honor the 40th anniversary of the moon landing by building a real-life version of the classic Atari game Lunar Lander. And you know what? It's pretty great.
Built using a pair of old PCs, some fishing wire, inkjet printer motors, spools and little lander models. You use a wheel to control where the lander is and a button to control the rockets, aiming your lander to its ideal landing position on the moon's surface. It only cost him $800 to build, and it'd be an impressive creation if it cost twice that. [PopSci]
