Random walkers located across the four sections of the screen cross and leave the canvas, mixing and integrating as they go.
Based on their veolocity, some Walkers will stay put, some will immediately exit to the side, others will mix and mingle.
I see this as the way different types of people spend their lives, some mingling and mixing with a long path symbolising a story to tell.
Others stay put, seemingly content to remain where they begin or perhaps not brave enough to explore the other corners of their realm.
