Yukao Nagemi
Digital artistYukao Nagemi (the artistic persona of Lucien Birgé) is a French digital artist, researcher, and live performer who explores the creative interplay between live drawing, code, and performative visuals. With a background bridging computer science, sound design, and visual art, his practice focuses on creating custom software tools that enable expressive, real-time digital creation. Nagemi frequently collaborates with musicians, dancers, and sound performers, developing dynamic computational systems where organic hand gestures are augmented and transformed through custom algorithmic processes.
porphyrograph ? the “electric” pen is a performative digital drawing project and live media installation centered on an expressive digital drawing interface developed by the artist. Designed to recreate and expand upon the tactile fluidity of traditional calligraphy, the “porphyrograph” functions as a virtual “electric pen” that translates physical gestural dynamics—such as speed, pressure, and trajectory—into rich, evolving visual textures and algorithmic brushstrokes in real time. Used extensively in live performance settings, the project bridges the gap between traditional drawing techniques and computational art, turning live mark-making into a dynamic visual instrument.
