I'm finding otherwise.
The key may be that thinking of Nv's as nerons vastly overestimates the Nv.
We should not be thinking of a photovore as a 2 neuron 'creature', its
phototropisim
is no better than many single celled creatures (that are phototropic in 3D).
What I've done is to use the chaotic control systems in geometric arangements
that
match the physical body of the device. By selecting the chaotic attractor and
geometery
is fairly simple to get controlled behaviors.
At least with the geometeries I've tested so far, which is very few.

Cheap shot Steve.
Its my contest entery, so I, unlike Mark have a set date for release.
Scalable in that higher ordered physical geometeries (of motive drivers) also
extend
the chaotic control circuitry without coherency problems seen in larger Nv
systems.
But behavioral complexity is not a direct function of scaling the device and
controller.
Behavioral complexity is a function of the chaotic attractor and the geometery.
There are
a number of things in this design that are at odds with the thinking outlined in
Living Machines.
