Installations
built to last.

A selection of immersive, interactive and event-based projects: from automated show control for Blanca Li's latest creation, to the audiovisual integration of exhibitions at the Palais de Tokyo.

Flagship project 2025

The show

Interweaving dance, live and electronic music, mixed reality, video, lighting and immersive sound (drawing on Ircam's cutting-edge technologies), and inspired by Hans Christian Andersen's emblematic eponymous tale (1847), the show L'Ombre resonates strikingly with our contemporary world and its innovations.

Facing the dancers and a percussionist, and fitted with a mixed-reality headset, the audience wanders through a fantastical world where the tangible and the virtual blur into one.

A 57-minute show.

L'Ombre — Blanca Li & Édith Canat de Chizy

Mixed-reality show · Dance · Live music IRCAM, Paris
Show control, synchronisation of every technical element of the show.

A scholar grants his shadow the ability to come to life and gain autonomy, so that it can break free and ultimately cast the human into darkness… A living, augmented performance, "L'Ombre" is a groundbreaking, hybrid project conceived by choreographer Blanca Li and composer Édith Canat de Chizy.

What Darkvalley brought
  • An ambitious set-up: 200 mixed-reality headsets, 44 performances, 10 dancers and one percussionist. At the heart of the project, we built a fully automated show control architecture, linking augmented reality, video projection (mapping), lighting and live sound across the space.
  • The IRCAM team used its innovative tuning and spatialisation systems across more than 96 loudspeakers, which we integrated into a precise, timecode-driven synchronisation chain.
  • A perfectly coordinated experience, where every visual or sonic effect moves in harmony with the choreography and the performers, ensuring a seamless run and consistent quality at every performance.

Exhibition 2024

SIGNAL — Mohammed Bourouissa, installation view at the Palais de Tokyo
Installation view · Palais de Tokyo
The exhibition

A multimedia exhibition exploring collective narratives rooted in intimate experiences: photographs, films, videos, music, digital installations, sculptures and objects, deployed throughout the spaces of the Palais de Tokyo.

The work brings together 19 screens and video players and 132 spatialised audio tracks, orchestrated as a single coherent whole.

SIGNAL — Mohammed Bourouissa

Multimedia exhibition · Photography · Video · Sound Palais de Tokyo
Show control, video synchronisation and spatialised sound diffusion.

An exhibition by Mohammed Bourouissa, where each space forms a fragment of a single collective narrative, between the intimate and the political.

What Darkvalley brought
  • Complete show control: automatic start-up and shutdown of the exhibition, sensor-triggered effects throughout the visitor route.
  • Synchronisation of the videos and spatialised audio tracks, spread across the museum's various spaces.
  • A manual control interface accessible from the museum's maintenance console or the artist's phone.

Installation 2025

L'Île au Corail — Simon Rouby, underwater panoramic projection
XR installation · Palais de la Porte Dorée
The installation

An immersive XR installation examining coral bleaching. Visitors move through panoramic projections of underwater landscapes; recognition of their gestures triggers visual transformations, set against audio accounts gathered from researchers in Mayotte.

Four HD video projectors compose an immersive, continuous and seamless panorama.

L'Île au Corail — Simon Rouby

Immersive XR installation · Hand-tracking · Projection Palais de la Porte Dorée
Show control, projector synchronisation and real-time gestural interaction.

An installation by Simon Rouby that turns the visitor's gesture into a moving narrative on the fragility of coral reefs.

What Darkvalley brought
  • Synchronisation of the 4 HD video projectors for a seamless immersive panorama.
  • Integration of real-time optical hand-tracking into a Unity pipeline driven by show control.
  • Integration into the existing audiovisual network of the Palais de la Porte Dorée, with no added infrastructure.
