In 1970, John Conway came up with a 1-player game called Game of Life. The Game of Life is a mathematical game that simulates 'colonies' that grow or die based on how crowded or lonely they are and is known for the way it creates a beautiful organic display out of randomness.
Here is a design for a simple electronic project that plays Conway's Game of Life. Make one kit and keep it on your desk, or attach multiple kit modules together to create a large display.
Originally created by Dropout Design, this revision adds a few extra features. The kit is very easy to make and an excellent first electronics/soldering project. It is perfect for workshops since at the end everyone can connect their completed module together.
The animated GIF above shows 4 modules connected together. Each kit comes unassembled and includes all parts necessary for one module.
