Two dimensional CA
The flatworm planaria zajiceki
Hitherto the CA image depicted a CA history. In the present experiment it depicts a two dimensional CA#600. You plant the seed ( = 1) as you did in previous experiments. The seed is called zygote. As it divides, additional layers are formed and the CA grows. All cells are descendants of the zygote. The worm is monoclonal. Each cell keeps its own time and when it gets old it dies. ( = 0). The worm advances forward in the direction of the arrow.

From the time of its birth each cell accumulates matter
which it gets from its predecessor. In this way cells age. When the accumulated
matter in a cell reaches a threshold, it dies. All cells in a column
constitute a process, which starts at the row of the zygote. They
get their matter only from cells in their column (=process). Since the worm
advances, cells stream away from the zygote. They stream toward their
graveyard. The size and appearance of a worm depends on its age structure.
Cells in the smaller worm die at the age of 20, and in the larger worm they
die at age 30.. The graph depict their age distribution.

The difference between 1-D and 2-D CA is by the way information is updated.
If each state (row) is updated sequentially, it is a 1D CA. If all states
(rows) are updated in parallel it is a 2D CA (planaria zajiceki). In a n-dimensional
CA, all n-dimensions are updated in parallel. WOB (Wisdom of the Body) updates
its myriad processes in parallel, and so does the WOB computer.
CA#600 is the first draft for a massively parallel nonlinear computer,
called here WOB computer. WOB stands for Wisdom Of the Body .It
consists of parallel processes of streaming cells, or numbers. Each cell
carries its own time . You may regard the process as byte, and the
cells as bits.
