In a retrospective point of view, Townsend said that the track was "basically structured noise containing a morse code for a math equation," and that during the recording of the album he watched a television program about mathematician Andrew Wiles about his solving of Fermat’s Last Theorem. "was a problem thought previously insolvable with a very elegant solution: X2 + Y2 = Z². Although I’m far from a mathematician, I enjoyed the thought that two opposing ways of thinking could be linked by a simple equation. I was just struck with that during the "Alien" time, and it just so happens that ‘Ziltoid 2’, ‘Z²’, is an answer for me—of how to proceed. It just seems to tie up everything, including Strapping, in a way that I think is satisfying."
