So, apparently this is what a functioning 16-bit arithmetic logic unit looks like... at least when it is designed in Minecraft. And that ain't the half of it! It seems that there are a whole bunch of folks who are taking the game, with its avatars, pitchforks, and immense landscape, and building computers and the like. Indeed, there is also a complete 8-bit CPU out there, which takes binary machine code and sends output to a line of torches. While we'd rather spend our time teaching our avatars to breakdance in Second Life, we do admire the hard work that clearly went into these projects.
