Retrofuturist Underwater Submarine Station QR Code for Posters

About this design

A cream and rust-brown submarine station hangs in teal water, crowned with a glass dome, tall white smokestacks and curling copper pipes, while fish drift past dark ruin silhouettes. The two square glowing monitor housings and the round hatch on the hull hide the finder squares. Checkered white panels and brown pipe openings carry the light and dark modules across the structure. Strong contrast between the pale plating and the dark rust fittings, plus the deep blue backdrop, keeps the pattern legible.
