Glider

Definition

A glider is a specific configuration in cellular automata, particularly in Conway's Game of Life, that moves across the grid over time. It is considered a spaceship because it can traverse the space of the grid while maintaining its structure. Gliders are important in demonstrating how simple rules can lead to complex behaviors and they help illustrate concepts of self-replication and interaction in cellular automata.
