built to last.

A selection of immersive, interactive and event-based projects: from real-time show control for the Urban Xperience experience built for UrbanSoccer, to the audiovisual integration of exhibitions at the Palais de Tokyo.

Flagship project 2026

Urban Xperience — UrbanSoccer Nanterre (La Défense)

Urban Xperience — UrbanSoccer Nanterre (La Défense)
Immersive experience · UrbanSoccer Nanterre
The experience

A world first designed for UrbanSoccer: Urban Xperience reinvents 5-a-side football (and up to 7!) as a 90-minute immersive experience, from the locker room to the podium. Personalisation, entrance tunnel, a match in a virtual stadium, Sports Bar and replays — every key play becomes a show.

On the touch kiosks, each player picks their team name, kit, number and anthem; their photo becomes an animated player card. Then the immersive corridor and the giant-screen introduction, 2 × 30 minutes of play in a 35,000-seat stadium, and finally the post-match highlights and interviews at the Sports Bar.

A 90-minute experience — from the locker room to the podium.

Immersive experience · Show control · 360° video & sound UrbanSoccer Nanterre (La Défense) — Soft opening 02.07.2026
Show control programming: real-time triggering and synchronisation of video, sound, lighting and effects.

5-a-side football like you've never felt it. Step into the atmosphere of the big games: a personalised 90-minute experience, a world first, where every match is unique — in a 35,000-seat virtual stadium just for your team.

What Darkvalley brought
  • The show-control core of the setup: a state machine built with Chataigne that triggers and synchronises the show's sequences in real time — tunnel entrance, team introductions, playing time and after-party.
  • Cueing all the partner systems — video (14 projectors forming a 35,000-seat virtual stadium), spatialised 360° sound, lighting, smoke jets at the goals and live generative effects — so every trigger lands in time with the action.
  • An architecture designed for live: instant recovery of the show if it restarts mid-operation, for identical quality at every session, continuously.

XR show 2025

L'Ombre — Blanca Li & Édith Canat de Chizy

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.

Show control, synchronization 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 synchronization 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.

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.

Multimedia exhibition · Photography · Video · Sound Palais de Tokyo
Show control, video synchronization 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.
  • Synchronization 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

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.

Immersive XR installation · Hand-tracking · Projection Palais de la Porte Dorée
Show control, projector synchronization 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
  • Synchronization 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.
