variations on basic rules

Using a little bit of magic between rows of cells (compute one row of cells then play with the row), I have found some interesting patterns. The rules used were some of the basic 255 rules.

between the lines

Question for the CA purists: why (or why not?) would it be bad to break away from the pure CA evolution as follows?

1)Compute initial config for the full row.
2)Looping
3)Compute next row according to CA rules.
4)MANIPULATE the row according to non CA rules.
5)Loop Again

(I am Assuming people experiment with this method).
On one hand it seems disruptive (going behind the back
of the CA!). On the other it seems rather natural (in the algorithmic sense, it does not seem as though it should matter if I throw in an extra manipulation step).

Within the NKS book, are the CAs usually rather pure (unlike above psuedo code)? Does the author actually get into "fancy" CAs (or does he stay away from the mess)?

Just Curious....Thanks.

Composition of rules and art examples with random rules

Intermediary steps of evaluation could be considered as compositions of rules.

I contributed examples featuring composition of random rules to the notebook attached to
