One hundred squares. One thousand the first day. Your work continues the next. Days turn into weeks. You stick to the simple rules you started with.
Many more years pass.
Your commitment to your strange project never wanes. A great section of the planet becomes covered by your very basic art. One morning, you awake to start the effort again, but receive an unexpected interruption - a rocket from earth zooms down from the heavens to your rescue. Soon, you are aboard it, returning home. So you go to look out his window, to get his perspective.
