Every geek needs socks that remind him or her of Atari games. These TechGuy socks should do the trick.
This sock pattern, written for supersoft, superlight, superwash sport weight yarn, is a great basic pattern that can be used to make your tech guy smart looking socks with just a touch of tech. Or, if your guy's not so geeky, leave out the tech and make regular guy socks. (Heck, knit the small size and make some for yourself!) For techy socks, use one of the charts provided or make your own. In fact, most of the images from old video games or computer screenshots are already pixelated for you. Just draw in the graph lines and you’ve got yourself a chart!
Magknits has the patterns and instructions here. Here's a good techno song to play why you are making them. (via Make)
