HanaHana 花華—Japanese meaning “blooming, flower“— takes the player in a harrowing and thrilling journey into the depths of their minds, bodies and senses: Imagine if Minecraft and Tilt Brush met in a Salvador Dalí painting. You are the first-person player of HanaHana 花華, the life-force in a surreal sandbox. Embodied in a swarm of molecules, you are granted the ability to teleport and to create. By teleporting you can explore anywhere. By creating you can sprout hands, grow chains of hands and construct anything you can imagine from this root component. Be part of this artistic journey, in which the community of players collectively create a new, hand-made metaverse.

The interactive experience was inspired by the wonderful Nico Robin from Manga "One Piece" who can replicate her body part thanks to the magic of the Hana Hana no Mi devil fruit. With HanaHana 花華 the magic of VR allow us to discover for ourselves how it feels like to have the special powers to digitally self-replicate to infinity.

Mélodie Mousset


Mélodie Mousset

Mélodie Mousset (*1981 in Abu Dhabi) is a french artist based in Zurich, Switzerland. Oscillating between virtual and physical realms, Mélodie's artistic investigations around the body unfolds in surrealist narratives through numerous media: performance, video, installation, photography, sculptures and interactive media. She received the Swiss Art Award for her first VR installation We were looking for ourselves in each other in 2015, and her work is regularly exhibited in Europe and internationally. Mélodie has been an associate professor at ECAL, Switzerland since 2015.
