In a Nutshell is an immersive and contemplative installation that invites visitors to place their heads inside a dome conceived as a heterotopia: an other space, enclosed yet open to an infinity of coexisting realities. Through the use of optical and motorized devices, visitors discover a multiplied landscape in which multiple worlds unfold simultaneously. The work offers a sensitive reflection on the subjectivity of perception and the possibility of inhabiting several realities at once.
