Can you tell me what's missing or not clear from the pageful of notes that 
I wrote around the formula (in the subpatch) ?

Cellular automata are always based on convolutions. It's just not always 
stated explicitly... most programmers would rather write nested for-loops 
than use something like [#convolve], you see.

First I will add an actual intro to convolutions in general (before I 
start talking about blurs and stuff) and maybe it will become clearer for 
cellular automata as well. If you have more questions then I will add 
something more if I know what to add in particular...
