A confessional box at Walden Festival 2026 where visitors confess their sins to a local AI priest, who grants absolution - and forwards the sins, anonymized and retold in an angel’s voice, to the Holy Toilet.

This year, our Walden floor at Zugvögel became Santo Nido: a church dedicated to a phoenix sect. Stained-glass windows, holy birds, an AI confessional, and a tower-clock that goes wild with the music. A lot of religious nonsense, and so much love for detail.

This year, our Walden Floor transformed into the PetroLoco gas station that has been the site of a battle between the oil oligarchs and the ecological fraction. Next to the floor and the usual interactive installations, you could also play real-life Tuxkart here.

An interactive, networked spaceship you can actually board: players complete (or sabotage) missions across a dozen physical interfaces - buttons, joysticks, LED boards, sensors, etc - to either launch the ship or doom it, with everything driven by a Python/ESP/Unity stack. It’s modular, auto-resets regularly, and scales to festival crowds without manual babysitting.

In 2024, for our Walden Floor at Zugvögel Festival, the visitor was immerged into the crash site of an alien spaceship, featuring multiple interactive installations next to our usual dancefloor.

For the last three years I’ve been part of the crew behind Fusion Festivals largest Floor: Palapa — a collectively built, ever-changing “city of the future” and dance floor. We turn a 1,200 m² tent into a dense skyline of handmade structures, layered light, and countless small details.
