+
+This visualization builds on the previous. Structurally the cortesian grid has
+been turned into an isometric one, but this is more of an environmental change
+than a behavioral one.
+
+Behavioral changes which were made:
+
+* When a live point is deciding its next spawn points, it first sorts the set of
+  empty adjacent points from closest-to-the-center to farthest. Then it randomly
+  chooses a number `n` between `0` to `N` (where `N` is the size of that sorted
+  set) and spawns new points in the first `n` points of the sorted set.
+
+* Each point is spawned with an attached color, where the color chosen is a
+  slightly different hue than its parent. The change is deterministic, so all
+  child points of the same generation have the same color.
+
+The second change is purely cosmetic, but does create a mesmerizing effect. The
+first change alters the behavior dramatically.
+
+In the previous visualization the points moved around in groups aimlessly. Now
+the groups are all competing for the same thing, the center, and as a result
+congregate and are able to be viewed as a larger whole.
+
+The constant churn of the whole takes many forms, from a spiral in the center,
+to waves crashing against each other, to outright chaos, to random purges of
+nearly all points. Each form lasts for only a few seconds before giving way to
+another.
