But to address the Ringtone issue, he's going about it the wrong way. Sampling over time based on a fixed width (centered around the initial starting point) ignores any changes in complexity that happen over time.
In the CA, time is top to bottom, the initial state is represented in the first row and each successive row indicates a state that happens as time progresses. Limiting the viewing window to the center 8 or so points does not paint an accurate picture of how the overall picture changes over time.
I would suggest sampling across the entire spectrum over overlapping time segments in a way that accurately represents the change in ocmplexity across the board, even if it condenses it.
