Lime Green Jigsaw Puzzle Abstract QR Code for Posters

About this design

A field of black and acid lime green jigsaw pieces frames a gray tiled ground, with ragged puzzle edges running around the border. Small square frames with circle and window motifs disguise the finder squares, while chunky black blocks, thin lime crack lines and diamond shapes carry the modules. Strong contrast between the dark blocks and the pale gray and bright green gaps keeps the pattern legible. A grungy, spray-painted texture softens the edges without muddying the shapes.
