Interlocking transit lines in red, blue, green, purple, yellow, and cyan form a complex network across a world map, with each colored route representing different metropolitan subway systems overlaid in a single composition. The lines flow and branch organically across continents, creating a dense, interconnected visual rhythm that transforms geographic borders into a unified system of human movement and connection. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
