Life3D implements the popular Game of Life in three dimensions. Live cells are represented by cubes. Each cell has 26 possible neighbors (including diagonals). For each step of the animation, cells with fewer than four neighbors die of loneliness, while cells with more than five neighbors die of overcrowding. An empty cell with exactly four neighbors becomes a new live cell.

The view of the playing board rotates slowly so you can view the board from all angles.

The keypad buttons in Table 1 provide control over the game.

Controls for Life3D
Pause the animation.
Resume the animation at its default speed.
Speed up the animation.
Slow down the animation.
Choose the previous preset configuration from an arbitrary list. The name of the configuration is shown at the top of the screen.
Choose the next preset configuration from the list.
Generate a random configuration and animate until it stabilizes or dies. If it dies, generate a new random configuration.
