Whoops! Looks like I may have spoken too soon yesterday when I mentioned Conway's Game of Life.
On Day 12, we're actually implementing a variation on Conway's Game of Life... Plant Life, that is. Whether or not a plant is around for the next generation depends on what the plant-life around it looks like on the previous generation.
I will give 100 internet points to anyone who submits a cool animation with their solution! I will also award 5 bonus internet points for each plant pun we get along the way. Good luck! I'm rooting for you!
