This cipher is pretty simple. Basically, you would write all of the letters in a grid, then rotate the grid 90° and read the characters back out. I first heard of this method when Mike posted to the Kryptos Group mailing list. I liked the method and decided to write up a neat little encoder. It was used to decode K3. I can insert the first half for you, then you just copy the decoded text back into the text area above and change the column width to 8 in order to see the secret message.

Spaces are rotated with the letters, enters (newlines) are not. Extra 'X' letters will be added if the number of columns does not divide evenly into the text length.
