In each of these sections, you interact with the computer to create interesting and colorful pictures. Think of the video display as an electronic artist's canvas. The cursor acts as your pen, paintbrush, or artist's tool as you develop your own unique pictures. Give free rein to your imagination as you and the computer explore this section of VIDEO-GRAPHS.
===="Color Life"====
"Color Life" is a computer activity based on a game developed by John Horton Conway, a British mathematician at the University of Cambridge. It graphically portrays how, within certain rules, living organisms can grow, move, and die. Your Texas Instruments module adds the dimension of color to this classic computer game. Thus, you can observe how the color of a new cell is determined by the colors of its "parents."
Before starting to play with "Color Life," let's briefly discuss the concept of the game and the rules under which the patterns change and develop. Imagine that your screen is a large piece of graph paper or a colorless checkerboard.
Each square is called a "cell," and it is either "alive" (colored in) or "not alive" (vacant). The cells change at certain specific intervals - called "generations" - according to set rules. Each cell reacts to the eight cells that surround it in the following manner:
:■ A cell that's alive in this generation and has either two or three of its eight neighboring cells alive will continue to live in the next generation.
:■ A cell that's alive in this generation, but has only one surrounding cell also alive, will die in the next generation from isolation.
:■ A living cell which has four or more of its surrounding cells which are also alive will die in the next generation from overcrowding.
:■ A cell that is not alive in the present generation, but has exactly three neighboring alive cells, will be born in the next generation.
In addition to the rules that determine whether a cell is alive or vacant, other factors specify the color of each living cell in TI "Color Life." The color of each new cell that's born is an average of the colors of its three parent cells. Thus this activity simulates the laws of genetic inheritance. Watch how the colors merge and change from generation to generation.
