Underwater Ruins Vector QR Code for Stickers

About this design

Sunken stone ruins with ancient columns, carved arches and drifting algae sit inside a round frame of teal and deep blue water. The tall column pedestals and the square stone blocks with dark recesses hide the finder squares, while the cracked wall at the center carries the modules as blotchy dark and pale patches. Strong contrast between shadowed gaps and lit stone keeps the pattern legible, and fine seaweed fronds and bubbles are kept to the edges. Rippling surface light at the top fades into dark water below.
