It all started with me forgetting that I had tweet notifications for Hack For Satan after trying to get their Defcon Badge, they tweeted the following
Happy Halloween. We have both a trick and a treat for you evil little shits. Which first though? http://infernal.business
The page had a picture from the last scene of The Seventh Seal (1957), and the word "Danse". If you viewed the source, there was a comment.

From this board, I thought of some moves that would win the game, but I tweeted it to them, and they responded with somthing peculiar.
Don't fuck up my board.
Others were getting similar responses, but I then considered it while at my pizza place on campus, and thought about it, could it be a bitmap or somthing, and then I realised, why would all the pieces avoid Row 1 and Column A. Like a truck, it hit me, Binary. I ran upstairs and found my work area was being used for a recording, so I jumped into a lab and hijacked a whiteboard, and wrote it out, I have converted it to readable text, check my twitter for my insane version. I considered all pieces to be a binary 1, and blank spots to be binary 0.

I chucked it into the URI for infernal.buisness and as a new URL, and it loaded exactly what I deserved, a rickroll. I DM'ed them on twitter, and was one of the first few people to get it, was an interesting challenge, but if I didnt have to use a whiteboard for my conversion, I could have done it faster and probs have been first, so thanks for that Taylor.
