Two things you can guarantee will never go out of fashion are wooly hats and retro game motifs, so why not go crazy with both? This lovely two-tone Space Invaders hat is the work of Vinny, over on Take Back the Knit.
Suitable for geeks of all ages, with or without earflaps, the hat pattern is available for free, here. I'm thinking slightly metallic yarn for the characters themselves would make for one very special hat.
