Conway's Game of Life in golang for your terminal

Overview

This is Conway's Game of Life (Highlife rules implemented as a console application in Go. Multiple concurrent simulations can be running at the same time in different windows. Additional rules have been added that simulate a genome with a gene for color and shape.

The complete rules are:

• Survive when there are 2 or 3 living neighbors
• Die with less than 2 or more than 3 neighbors
• Born when there are exactly 3 or 6 neighbors (highlife)
• When a new cell is born, it takes on the color of the majority its parents or if there is no majority, a random color will be chosen from the set of colors present in the parents.
• When a new cell is born, it takes on the shape of the majority of its parents or if there is no majority, a random shape will be chosen from the set of shapes present in the parents.
• With each birth, there is a 10% chance it will take on a random color (mutation)
• With each birth, there is a 10% chance it will take on a random shape (mutation)
