Conway's Game of Life

I figured a good learning exercise for checking out <canvas> would be to implement a small example of Conway's Game of Life using the canvas for drawing. Here's the result.

This implementation has a small twist, where as a particular cell stays alive through generations (i.e., as it ages), the shade of the cell gets darker until it turns black.

Start out by clicking grid cells to create an initial pattern, or use of the sample patterns below. Once the initial pattern is set, click 'Go' to start the game.

Some initial patterns to try:

• Still lives - Nothing generated, nothing dying
• Basic 2-period oscillators
• Pulsar - 3-period oscillator
• Pulsar generator - Eventually generates a pulsar
• R-pentomino - Lots of complexity from 5 initial cells. Eventually stabilizes arounf gen 250
• Pentadecathlon - A 15-period oscillator
• Queen Bee Shuttle - 30-period oscillator where a queen bee travels between two blocks.
• 2 Lightweight space ships - The bottom one turns into a glider when it reaches the edge
• Flower of Eden - Dissolves into nothing, but pretty
