Snapshot 1: If all the rows are redrawn flush to the left border the structured region becomes more obvious. In fact, this shifted version of rule 30 can be emulated directly by rule 1,048,560 in the

rule space. Rule 30 as an 8-bit binary number is 00011110, while rule 1,048,560 as a 32-bit binary number is 0000-0000-0000-1111-1111-1111-1111-0000. Each bit of rule 30 expands to 4 bits of rule 1,048,560.
Snapshot 2: The regularity of the right-hand side is simpler. After the first 8 rows, the rows can be naturally grouped in powers of 2 starting with 8 rows, then 16, then 32, then 64, and so on.
