This example shows the difference between using anarchy to randomize the order of the different "galaxies." You can view the source code of this page to see how the code is written.
On the left, each tile has an independent 2% chance of being blue and 8% chance of being red. On the right, 2 out of the 100 tiles will always be blue, and an additional 8 will always be red. One or the other might be more accurate in different simulation contexts, and they also produce very different experiences in a game context.
