Bubble-Space is a virtual reality device created in 2019. It envelops the spectator in a pink and blue bubble. Equipped with a controller, he/she is invited to modulate, making the pink matter move in real time creating a link between spaces and bodies. Bubble-Space offers a sensitive experience of virtual materials that reveals potential in-between spaces. Bubble-Space was presented at the World XR Forum festival of Mixed Realities (VR AR XR) in Switzerland in Crans-Montana.
