+ +This visualization follows a few simple rules: + +* Any point can only be occupied by a single node. A point may be alive (filled) + or dead (empty). + +* Every tick each live point picks from 0 to N new points to spawn, where N is + the number of empty adjacent points to it. If it picks 0, it becomes dead. + +* Each line indicates the parent of a point. Lines have an arbitrary lifetime of + a few ticks. When a dead point's line is cleaned up so is it. + +The resulting behavior is somewhere between [Conway's Game of +Life](https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life) and white noise. +Though each point operates independently, they tend to move together in groups. +When two groups collide head on they tend to cancel each other out, killing most +of both. When they meet while both heading in a common direction they tend to +peacefully merge towards that direction. + +Sometimes their world becomes so cluttered there's hardly room to move. +Sometimes a major coincidence of events leads to multiple groups canceling each +other at once, opening up the world and allowing for an explosion of new growth. + +Some groups spiral about a single point, sustaining themselves and defending +from outside groups in the same movement. This doesn't last for very long. + +The performance of this visualization is not very optimized, and will probably +eat up your CPU like nothing else. Most of the slowness comes from drawing the +lines; since there's so many individual small ones it's quite cumbersome to do. -- cgit v1.2.3
