The patterns etched into each printed circuit board are generated by an algorithm known as differential growth, which mimics naturally occurring organic structures. Rather than being found embedded in stone or leaf, the pattern is etched onto a plate of copper, masked with black epoxy resin and retraced in silver solder. The result is a labyrinth: winding paths that catch and reflect light, forming an almost sculptural surface.

Typically incorporated inside everyday electronic devices, printed circuit boards carry digital and analog signals across traces sometimes no thicker than a strand of hair. Here, however, they carry heat. Each trace is precisely measured so that, when electricity is applied, the resulting resistance produces just enough heat to activate the opposite side of the board. This surface is coated with thermochromic ink. As a trace heats up, the ink shifts from black to transparent, revealing itself beneath. As long as current flows, this window remains open; as the board cools, it gradually closes, returning the surface to black.

The maze responds directly to its environment. In colder conditions, the paths take longer to heat; in warmer air, they cool more slowly. What emerges is a continuous exchange between voltage, heat, and surroundings.
