-This visualization builds on the previous. Structurally the cartesian 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. It then chooses
- a number `n` between `0` to `N` (where `N` is the sorted set's size) and
- spawns new points from the first `n` points of the sorted set. `n` is chosen
- based on:
-
- * The live point's linear distance from the center.
-
- * A random multiplier.
-
-* 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. Only the points which compete for
-the center are able to reproduce, but by the same token are more likely to be
-starved out by other points doing the same.
-
-In the previous visualization the points moved around in groups aimlessly. Now
-the groups are all competing for the same thing, the center. As a result they
-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.
