I wish I knew the necessary skills to make this scarf right now. I don't, but being the fiance of a major computer nerd, I will learn intarsia just for this (although I might turn it into a blanket)
I just wanted to post it in case you guys know any computer nerds out there that you want to knit for. What's cool about this binary scarf is that you can actually change the placement of the 1's and 0's to make your own binary message, like "I love you", or if you're passive aggressive and you know the intended recipient doesn't read binary, "You suck". [Joking, sort of....]
There might be websites that will generate a binary message for you, but if not it's a simple task...just look up how to write in binary.
