Isometric Underwater Dome Base QR Code for Posters

About this design

An isometric underwater research base sits under a clear glass dome, on a translucent teal block with yellow fish, red coral and a curled pipe hose. Three square sunken pools with dark rims stand in for the finder squares. The stone-tiled walkways, moss patches and seaweed tufts carry the modules in dark and pale blocks. Light stone against shadowed gaps keeps the pattern readable, while bubbles and a small dome above add depth without crowding the grid.
