Sumi-e Calligraphy Brushstroke QR Code Art

About this design

Bold black and rust-brown brushstrokes sweep across a pale white ground, mixing loose calligraphic gestures with ink dots and small seal-style characters. Three square frames built from thick vertical and horizontal strokes, two holding dark glyphs and one a brown seal block, disguise the finder squares. The remaining strokes and splatters carry the modules as dense dark marks against the empty background. Strong black-on-white contrast and the even spread of ink keep the pattern clear, while the brown bristle texture adds warmth.
