Jesse McPherson, obviously a programmer, is the owner of the above knuckle tattoos. He said he got them done at “some pirate themed tattoo shop in LA”. He chose the font that he normally codes in, blew it up to get it pixelated and then did one hand blue and the other hand black to symbolize the always useful syntax highlighting. In addition to the knuckle tattoos, Jesse’s also got “code” tattooed on his inner lip.
By the way, I highly recommend getting tattoos like this AFTER you’ve learned to touch-type. Or you should get the home row keys like this guy did.
