Crossing Paths
64x64 LEDs, opal acrylic sheet and wooden frame
The phrase ‘crossing paths’ describes a meeting between two people, usually by chance.
This artwork began as a study of random movement. The first half of the piece is built around some simple rules, borrowed from the early computer game ‘Snake’, which was too obvious a visual reference to ignore:
· A snake chooses a random direction for each new step but tries to avoid colliding with itself.
· If ‘food’ of a certain colour appears, the snake will move towards the food and eat it.
· Eating food makes the snake longer.
For a snake to get longer it must remember a growing list of the locations it has just visited. I imagined that each item of food was an event that the snake would encounter, and then carry with it on its journey. Just as the tail of the snake represents something for it to avoid in the future, so too do our past experiences have an impact on the decisions we make moving forwards. As more of the snakes’ histories are revealed, patterns begin to emerge-like a picture of society, showing regions where many snakes have been, and others where none have ventured. Individual movements become hidden within the complex map of interconnected pasts.
From this point, the snakes’ freedom becomes guided not only by their previous decisions, but also by external influences that set out which future paths are available to them. Increasingly intricate zones dictate the routes snakes must take to reach each other, and it is only through head-on collisions, by crossing paths, that the snakes are able to progress through the piece. This artwork reminded me that although crossing paths with someone in the present is a rare event, our pasts are deeply and continuously intertwined.

Henna Koivusalo on ‘Crossing Paths’ by Liam Taylor-West
The snakes in Liam's piece move quasi-randomly over the whole space at first, and then start tracing the constructions of different famous fractal patterns, which slowly emerge from the chaotic movement. The term fractal doesn't have a rigorous mathematical definition, but it often refers to patterns created by iterating some deformation rule.
The first fractal pattern that the snakes reveal is the Sierpinski Carpet, discovered by Waclaw Sierpinski in 1916. Its construction is based on repeatedly making square holes in the middle of smaller and smaller squares, which, when continued forever, leads to an infinitely intricate lace pattern. The next fractal the snakes discover for us is the pattern of a space-filling curve known as the Hilbert curve. This pattern was first defined by David Hilbert in 1891, and has the property that, again when continued forever, becomes `infinitely wiggly' and fills the whole square. From the perspective of the snakes, it matters a great deal that some snakes that seem to be very close together, can take arbitrarily long to actually reach each other. This is due to their movement being restricted to the construction of the Hilbert curve.
The scientific process of finding and analysing new patterns is quite like the movement of the snakes -- they wiggle about and sometimes travel across with purpose, but it takes a while before any order arises from the chaos, before any answers emerge from confusion. But when it does, there's a tremendous beauty in the discovery.
