Welcome to <rtbt>

Great you're here!

Welcome to a bunch of burning hearts who are about to create a crazy art installation to unite the world. Dive in and follow your heart.

You'll find that <rtbt> is more than meets the eye. It's bundled creative energy from all over the world – in one piece of art.


Our 🫀 is asking for your support:


(pronounced: art beat)

<rtbt> represents the connective creative spirit of all human beings: A big heart-shaped interactive video art installation to be erected in Switzerland and in the desert at Burning Man 2023, <rtbt> unites and inspires the community to participate and experience a collectively-created video art piece.

<rtbt>: Feel united in creativity – and connected in the heart.



During the Special Week of the BFH in Biel, it begins to beat: Probably the most imposing, interactive art installation of a human heart to date, sustainably constructed from wood. For this project, which is as creative as it is symbolic, creative minds and experts from a wide range of disciplines are working together courageously - with far-reaching ambitions.

physical description of <rtbt>

<rtbt> is a huge human heart-shaped video art sculpture – including video recording (outside) & play devices (inside). The framework material is wood. The structure will be covered by cladding (weatherproof fabric or sheet wood).

The heart is surrounded by 5 video recording stations on stands (recording tools are provided) — each including an inspiration e.g.: «Show your love» / «express your feelings» / «dance for us» / «make a grimace» etc. Visitors can also suggest inspiration themes… They may interact by recording a theme-specific video of 10 sec. Inside the heart, you'll find a lounging area/hammock (innovative net solution made from recycled material) where they can chill — and watch the collectively created video sequences on a big video screen.

A unique light concept that emphasizes the heart-shaped architecture is integrated > at night the heart glows from within.

Loudspeakers provide the regular and calming sound of a real human heartbeat.


<rtbt> unites radical inclusion, self-expression, communal effort, interactivity and different art forms (art installation meets video, dancing, singing, talking, acting etc.) Experience it alone, with friends or strangers in many playful, creative and meaningful ways. The powerful and emotional meaning of the heart resonates in each of us. <rtbt> invites participants to enter the uniting creative heart energy and inspires them to participate in the artwork: to experience the creative connectivity of the community — by watching the collectively-created video art piece together.

With the heart installation and software we only provide the «frame». The «core-artwork» is created, changed and experienced by the community itself — actively or passively with recorded videos and experiences inside the heart. They interact with each other and with the artwork — in fact their interaction IS the artwork.

Participants may interact in their own way — and keep <rtbt> «alive»: in constant motion, in constant interaction.

the philosophy

We believe in the power of creative energy: We are all connected and united in creativity.

Since the heart shape represents the emotional connectivity between all human beings, its structure visualizes this invisible net of connections. The recorded video clips stand for our creative actions in life. By joining them specifically together (with our software) the community is constantly creating a unique and surprising piece of video art: funny, thoughtful or weird – we will see...

Everyone is welcome to participate, to make a difference. Artist or not – we are all creative souls. We respect everyone's privacy and provide an inspiring «safe space»: cameras are filming on-demand and recorded videos are exclusively used at the Burning Man.

We cordially invite one and all to go inside the(ir) heart(s), to enjoy the power of collective creation and new built connections within the community. Push the record button and become a part of the big heart. Together we are one <rtbt>.


<rtbt> features a light show made out of 64x4m (209x13ft) WS2812b LED-strips (total of 7680 px) – arranged in 32 lines of 8m (26ft), placed on both sides of the vertical elements of the structure, facing sideways, the light will be only seen indirectly. All cabling & wiring will be hidden inside the structure, creating an amazing experience while encountering the artwork.

The fabric of the inner room allows the light to shine inwards. When a video is recorded, the transfer from the camera to the heart is displayed as a LED stripe in the ground – symbolizing a bloodstream.

Each video sequence, assembled according to the theme, is given its own color code, in which the heart is illuminated: an enchanting color spectacle.

All cameras will be equipped with LED rings that provide good illumination of the people standing in front of it (& visibility for safety reasons).

Building / during burn: If guy wires are needed for structural safety they will have battery-powered fairy lights (structure visibility).

build materials

<rtbt> We rely on laminated veneer lumber panels, that will be CNC-cut (LVL-Q panels) (Thickness: 2.7’’).

As they are connected with each other in a waffle structure, they support each other in all directions. The bearing structure will be covered with either fabric (e.g. stage molton, attached with a staple gun) or, as an alternative, wood planking.

We are currently looking for a stable material to reshape / display the 3D polygon structure.
