Isometric Underwater Base 3D QR Code for Posters

About this design

An isometric underwater base control room sits on a floating tile slab, with glass walls showing pink and orange coral, tropical fish and drifting bubbles. Three square sunken pools with pale rims act as the finder squares, while the pale blue tiles of the floor carry the modules against dark blue gaps. Bubble domes, small coral clusters and curved walkways fill the lower edge without crossing the data area. The tile contrast and the dark background keep the pattern crisp, and a glowing glass orb floats off the front corner.
