Hi there!

Playfool is a collective established by Daniel Coppen (UK) and Saki Maruyama (JP). Both graduates from the Royal College of Art, their work employs play as a mediator to intervene in the relationship between humans and technology.

Spanning across the realms of product, installation and multimedia, their work blends thorough research, new technology, and thoughtful aesthetics into playable experiences.

Playfool’s works have been widely exhibited at institutions such as Victoria & Albert Museum in London and MAK - Museum of Applied Arts in Vienna.
