Hitofude Ryu is the Japanese art of painting a dragon in one stroke with a brush. It is a type of art called “sumi-e,” or Japanese ink painting. Our course is on digital art, which allows the artist to undo or redo anything they do on their artwork; any mistake can erased with a simple command-Z. However, since these dragons are painted in a single stroke, with the brush never leaving the paper from start to end. I think these artworks are very valuable since they could have only been made at that exact moment. As the painters are human, the dragons would look slightly different if they were drawn even just a minute later.
