Ok, I thought about creating a maze in the front yard but settled with just sculpting the grass this year. We have a boundary between our front yard and the street that is technically owned by the HOA across from us, though with the adverse possession law, who knows? This year I left a swathe of grass unmowed at the bottom of our property to act as a natural fence. Just for fun, I'm leaving an unmowed circle in the middle of the front area. The grass is about to bloom so the pollen will be tough for a few weeks, but it's tough for me anyway.
If the neighbors complain, I can say aliens created a reverse crop circle in our yard.
