Ryoji Ikeda is known for creating immersive, experiential installations that often use technology to create sensory overload. For example, in his series of installations called "datamatics," Ikeda explored the aesthetics of data by creating visual and auditory experiences that were based on data sets. These installations often featured projections of data onto screens, as well as soundscapes that were generated by data. Ikeda's "datamatics" installations were meant to be immersive, and they were designed to engage the senses of the viewer in a way that was both disorienting and hypnotic.
Ikeda's work is often minimalist and abstract, and he is known for his use of mathematical formulas and scientific principles in his compositions. For example, in "The Transfinite," which was exhibited at the Centre Pompidou in Paris in 2011, Ikeda created an installation that featured projections of mathematical formulas onto a screen. The formulas were meant to be visual representations of the concept of the transfinite, which is a mathematical term that refers to numbers that are larger than the infinite. The installation was meant to be an immersive experience, and visitors were encouraged to walk through the space and explore the projections.
In addition to his work as an artist, Ikeda is also a composer, and he has released several solo albums of electronic music. He is also a member of the Japanese noise music group CCCC, which is known for its experimental, avant-garde sound. Ikeda's music is often minimalist and abstract, and it often incorporates elements of noise, electronic music, and field recordings.
