Retro Psychedelic Abstract Pattern QR Code for Posters

About this design

A busy 1970s style poster field of mustard yellow, teal, magenta and red, packed with swirls, halftone dots, striped wedges and round eye-like shapes. Three nested concentric squares, each with a solid circle at its heart, disguise the finder squares. The data modules are carried by the tangle of dark blobs, ribbed curves and small black dots scattered through the yellow ground. Dark outlines and strong colour contrast keep the pattern readable, while fine hatching adds texture without crowding the main shapes.
