WN: You also have two other sculptures on the CIA grounds that are near the Kryptos sculpture. Are they related to Kryptos in some way?
Sanborn: Well, all I’ll say is basically I designed the piece(s) to act (such that) this part is easy, the next part is less easy, the next part is the most difficult. So if you consider the entrance to the new CIA building (to be) the entrance to the agency, the piece that’s out front is the most simplistic, basic code that there is. Then they get more sophisticated the further you (go onto the campus).
WN: Do the other pieces in the courtyard have clues for solving Kryptos?
Sanborn: I won’t say.
(WIRED Interview, 01/20/05)


Is the Morse code in the “courtyard”?  I thought it was in front of the new building?

Are the “two” pieces just the two slabs with Morse Code?

This is another Sanborn quote that doesn’t actually make sense.  It’s the Morse code and the copperplate right?  There’s no real going “further” but more of a sudden stop at more sophisticated.  Maybe in his mind it’s this grand process of going from easy to hard but I just don’t see it.  The Morse code is not actually a cipher and then you get two identical ciphers, K3 and the unsolved and implicitly ridiculously hard to solve K4.

Am I missing something or is this just a problem of perspective?
