EXAMPLE
From Michael De Vlieger, Dec 02 2015: (Start)
First 8 rows, showing surrounding context at left, cells generated by the initial cell at center, and the binary equivalent at right where leading zeros are lost:
0 1 -> 1
1 0 0 0 -> 0
0 1 0 1 0 1 -> 10101
1 0 0 0 0 0 0 0 -> 0
0 1 0 1 1 1 1 1 0 1 -> 101111101
1 0 0 0 1 0 0 0 1 0 0 0 -> 10001000
