Conway’s game of life, who hasn't heard of it :) Well for me it has been a toy and a joy for many years. Check Wikipedia for an explanation of Conway’s life. As life on it's own has a tendency to die out, I figured to introduce another life form that interacts with the cellular automata, to keep things going.

• These 'bugs' that I introduced eat the life cells
• The more they eat, the more they grow - to a certain extent
• As they move, they burn energy and eventually shrink again
• They leave droppings behind in the form of small life gliders
• When they have grown enough, they can find a mate to reproduce with
• Their offspring inherits properties like how much and often they turn
• They die when they don't get enough food and then scatter - in life cells :)

Life can be controlled with the START, STOP, STEP and STEP BACK buttons, which are quite self-explanatory. The following shortcut keys can be used as well:

• down - stop
• up - start
• right - step
• return - restart life
• insert - toggle ‘trails’
• delete - clear life
• click - draw life
