French artist David Bayo uses charcoal, graphite, or ink on paper to create stunning monochromatic portraits and landscapes. In the timelapse video above, which was spotted by Laughing Squid, Bayo takes a cue from Georges Seurat and Paul Signac and uses more than 1 million tiny pencil dots to craft a detailed drawing of a woman. The entire work reportedly took Bayo over 90 hours to finish—but thanks to the magic of modern cinematography, you can watch him complete the arduous project in only three minutes.
