Optical Illusion Circle Maze

The maze below is one that I drew upon an iPad along on a bumpy bus ride in the Northern parts of israel. As you can see, the maze come out crisp and clear, even though the bus ride was exceedingly "aggressive", as is probably the best way to describe with, with people vomiting from the nausiating motion, and luggage and bags falling into the aisle from all the shifting.
As you can see, the image is of a circle using variations of lines going in different directions to create the optical illusion that you see here in the maze. You can see more Yonatan Frimer Mazes and feel free to share your ideas and feedback here.
