“Nature/Code/Drawing,” an exhibition of plotter drawings by Hiromasa Fukaji and Junichiro Horikawa, opens at CUBE 1,2,3 in Tokyo, showing exceedingly natural, but algorithmically generated forms. In joining forces—Horikawa on programming, Fukaji on plotting—the two designers attempt to express nature’s complexity by simulating the delicate interplay of logic and chaos that governs the world. They reveal process too, drawing new forms during the exhibition.
