Brian,

No, if you reread my post, it was in response to your post about the logic gate node, not L-Systems.

Cellular Automaton replies on conditional logic to test each cell's adjacent neighbours at each iteration to operate,
so it should be possible to build in NE with the use of logic nodes.

See the wikipedia entry for generative rules:
