Bustling cities are transformed into vibrantly colored maps depicting eroding terrains in the gorgeous series Flowing City Map by Geneva-based illustrator Chaotic Atmospheres. Chaotic Atmospheres began by rendering city maps in the program World Machine, a 3D terrain software. The illustrator then combined the maps with procedural terrains in order to achieve the right amount of “erosion flow.” “I wanted to represent the influence of cities on their environment as a kind of invisible fluid that overflows from the city to its surrounding,” the artist explains. Erosion and natural features take the form of streaks of color that flow throughout the densely packed metropolis like water, turning the landscape into a dreamy plane of ripples and currents.
