-I took a step back from my high ambitions from before, and just focused on the neural nets, leaving
-out all the genes for body and behavior. It's all in place now, and the overall structure of the code
-has begun to stabilize enough that I can start building on it. My next step will be
-to implement some genes to control the body--at present, all the genes are devoted to building the
-brain. The arkons all have the same propulsion style:
+Another big redesign. Using the physics engine to move them around turned out to be a big headache,
+so now I move them around on a fixed grid using SKActions. Now, with any luck, I'll get some cool
+genetic stuff going, like some genes to control the body--at present, all the genes are devoted to building the
+brain.

+Arkons currently have four sets of senses, two sets for tracking external stimuli and two
+for tracking internal stimuli:
 
-The power and duration of the forward motion and rotation are under genetic control, as well as the duration of
-the stops.

-Arkons currently have eight senses. Three of the senses are 2D vectors requiring two inputs, and
-the other five ar scalars. The senses are:
-
-* Velocity
-* Angular velocity
+* Hunger level
 * Oxygen level
 * Location in the world, as (r, Θ) to the origin
-* Very short-range detection of food, as (r, Θ) to the closest morsel, and a count of how many are sensed
-* Very short-range detection of other arkons, as (r, Θ) to the closest arkon, and a count of how many are sensed
+* Very short-range detection of food and other arkons (which can be eaten if the attacker is big
+enough), as (relative position, nutrition value) pairs
 
 I don't have a road map, because I lack discipline. Here are some alleyways I will probably explore.

   * Body and behavior genes
