Proximity is 8/9ths (or 4/5ths) of a Relationship

Drag your cursor across the grid. This visualization is an homage to the Moore neighborhood.[1] It consists of a single cell surrounded by eight neighboring cells. It’s closely related to the Von Neumann neighborhood which consists of a single cell and four adjacent cells at top, bottom, left, and right. The Von Neumann neighborhood[2] functions at the heart of the algorithm used in my visualization for Axelrod’s model of The Disemination of Culture. And it’s also central to the working of my implementation of the classic plastic toy, the Sliding Number Puzzle.
