Interactive and participative mapping

This artwork can take place in front of the facade of a building during the night in order to become a giant interactive mapping in the urban space. It can also be shown in a smaller space, on the wall of an exhibition room.

Synergies is an interactive, collective and performative digital artwork installation renewing the approach of the video mapping.
The artwork’s software enables creating in real time infinite narrative scenes by manipulating several “video elements“ and “image elements“: the generative and participatory bricks of the installation.

Synergies proposes to build imaginary mechanics: it allows improbable and random meetings between people, situations and objects. These virtual and imaginary mechanics evolve with people’s interactions. This interactive and collective artwork is able to bring spectators together in unpredictable stagings.

Synergies offers a simple and singular mapping: A video projector projects the software’s images on a wall, a building facade or any other space . Real and virtual images are mixed together.

Synergies offers a space of expression and abstraction.
The work’s device enables people to interact all together. It is easy and accessible to everybody.
An interaction space is facing to the videoprojection. It consists of a camera and a staging space with a black background.


In the area of interaction, the spectator can:

either use a digital tablet, to pick an element from the image library, to show it in front of the camera, and then to film and stage it. Static or animated visual elements are suggested in this library: moving characters (walking, running, jumping, manipulating etc...), objects like bouncing balls, umbrellas, books, candles, etc... or natural elements like animals, plants, etc...

either be a new element on stage by filming himself in action for a few seconds. He can choose to show only his hands, his face, his full body or make any other proposal.It makes so many ephemeral chain (actions) reactions possible, evolving along with the public’s creative ideas. After some time, we all clear it up to let people create a new scene.

The sizes and the orientations of the elements can be easily modified with the artwork’s device: for example tiny characters can be in front of huge objects.



All static or animated visual elements are part of a large corpus of real and imaginary graphic objects. Mixing all these elements can create infinite virtual mechanics. The stories to be invented can be enriched by all these items.

The “video elements“ have different durations and are played on a loop. Each one plays independently an act of the work. The totality can be arranged with several possibilities in order to create scenarios in constant transformation. The evolving scenario of this creation offers participants a large part of improvisation.

In this creation, everyone’s cooperation contributes to the production of a collective artwork. This freedom of action benefits our participatory and interactive artworks. The result always offers unexpected moments of emotions.

When too much elements are placed by the visitors, the scene can easily be cancelled in order to let the space empty for new proposals.
The artwork is constantly renewed throughout the exhibition’s duration.


Synergies: between ecosystems and machines

Each experience of the artwork is always different. In reference to Raymond Queneau’s combinatorial poetry, Cent mille milliards de poèmes, the several video elements and image elements integrated into the digital artwork enable the creation of scenes with unexpected and infinite interactions between the elements of these virtual mechanics: between humans, objects, situations,... Each scenario simulates a machine producing virtual energy. The chain reactions are made with mechanical elements: cogs, chains, strings,... and human elements: hands, feet, faces, actions,...

These imaginary mechanics are inspired by the Shadow Theatre, George Méliès’s cinema, and refers to Goldberg’s machines, designed to perform a simple task in an intentionally complex manner, most often with a chain reaction.

Like an ecosystem, the different elements are interdependent and produce together a virtual energy.


Possible layout of the digital work

Synergies is in perpetual transformation.

This artwork can be shown in a classic exhibition room or it can be displayed during the night in front of a building in the urban space in order to generate a large interactive video mapping.

Here are some examples of possible scenarios made with several “video elements“ and “image elements“.
