The Spiral Cipher is a surprisingly simple code using a continual spiral to encode your message. It starts off as A=1 B=2 and so on, like the A1Z26 except for a few numbers representing punctuation. After the second time you use an a in your message it would be 30 because it is the second number above A on the Spiral, so B would be 31 the second time. This picture ends at 58 but the spiral is really never ending. The third time you use A it would be 59 and the fourth would be 88 and so on.
