Keys of Light is an interactive piano installation for everyone, allowing the audience to co-create the work by playing the piano. Every note creates a pulse of light or visual element that represents the nature of that tone, projected into the surrounding architecture. In doing so, it becomes an extension of the performance, challenging the player to explore harmony between music, projection mapping and architecture.

The installation is modular and capable of adapting to any environment and location. Several exhibitions of ‘Keys of Light’ have proven this work to be ideal for light- and art festivals and a great platform for local culture and art to merge in one magical experience.

It doesn’t matter where we are, whether it’s Belgium, France, Israel or Singapore, Keys of Light unites people and creates a once-in-a-lifetime immersive experience.

Keys of Light serves as a platform for talent. Every edition encourages local talents to participate and share their skills with the audience. From local conservatory students, to well known pianists and child prodigies – the interactive piano installation offers a stage with an audiovisual experience for both the musician and the audience.

This way we aim to stimulate culture on every light festival and event we participate in.

Festival of Light Ghent, Belgium was the very first edition of Keys of Light. After several participations at this festival with projection mapping shows, our interactive piano installation was hosted at Bisdomplein in Ghent. We projected on to three buildings for this project.

Our designers followed the shapes and lines of the architecture on-site, to create visual designs that accentuated Belgian characteristics of the buildings.

Our animation designs combined with professional technical production, brought the environment to life.



iLight Singapore


Singapore is known as Asia’s greenest city and innovative environmentally friendly ideas.
We were more than happy to take part in the ideology of this beautiful city during the iLight Festival.

Inspired by the mesmerising Peranakan culture and style, our designers created unique colour palettes to honour the heritage while accentuating the beautiful nature in the Fort Canning Park.
As our interactive installation was located on a hill, we playfully integrated the light tower that served as an eye catcher.

Kurhaus Scheveingen


Kurhaus, or Grand Hotel Amrâth Kurhaus Den Haag, is one of the most famous hotels in Den Haag. Located at the seaside in Scheveningen, it is a popular location for various artists and influential guests.

In occasion of the festival Feest aan Zee, an event in Den Haag connecting seaside to city, we were asked to present our interactive piano installation Keys of Light at the Kurhaus. The location is well known for the famous café Crazy Piano’s, hosting many live performances and artists. It was a great pleasure introducing piano performances on an other level. Inspired by the beautiful architecture of Kurhaus, our designers created unique animations that were projected when playing the piano.

Various famous Dutch artists such as Wibi Soerjadi,  Cor Bakker and Jan Vayne gave their performance on Keys of Light, creating an unforgettable immersive experience.



Lumina Portugal


The LUMINA Festival of Light, held in Cascais Portugal, showcases international artists with light installations, immersive video mappings, performances, parades and interactive projects.
We were asked to participate with our interactive piano installation Keys of Light.

Cascais Cultural Center served as our canvas and inspiration for the animation designs. In collaboration with interactive-designer Adriaan Wormgoor, we were able to create unique variations to be discovered by the audience. Every key triggers a different outcome on the building. Keys of Light became very popular among children and adults.

Jerusalem Festival of Light

Keys of Light Visual Design


Jerusalem  – one of the oldest cities in the world and a spiritual place for the three major religions: Christianity, Islam and Judaism. It has a rich history dating to 4000 BC. The Old City – a walled area within Jerusalem – is divided into four parts: the Christian Quarter, Muslim Quarter, Armenian Quarter and Jewish Quarter.

Once every year, the historic Old City turns into a unique festival that lights up the whole area. Hundreds of thousands of visitors travel to Jerusalem to wander through the picturesque streets discovering many amazing art installation that the Light Festival has to offer. Jerusalem Festival of Light exhibits a variety of multimedia artwork, such as 3D- installations, video artwork, sound- and light shows and interactive installations. Keys of Light traveled to this beautiful location in the Old City.


Every time our interactive piano installation Keys of Light travels to a new destination, it becomes a unique site specific artwork. Investigating the place, it’s history and it’s values, our team creates a one-of-a-kind installation that evolves and transforms leaving no performance the same. For this particular Light Festival in Jerusalem we presented our art work at the square of the Davidson Centre. Davidson Centre is an Archeological Park in Jerusalem, located near the Western Wall in the Old City. This one of the top tourist attractions has a great historical and archeological significance, where you can find remains dating from the First and Second Temple period. Off course this extraordinary location asked for an extraordinary installation. For the first time we have designed our interactive installation using no projectors!

In close collaboration with interactive designer Adriaan Wormgoor, we have created a ‘light-tree’ installation with the piano as it’s heart. 72 DMX lights and 168 meters of LED tubes consisting of 10752 LED lights in total, were all controlled separately by our software, immersing the audience with an illuminated experience of music and light. The installation was programmed as such, so it recognises the intensity of the play, reacting accordingly with a variation of light and color compositions. Every piano key triggers a different composition in space, creating a dynamic interaction between the piano player and it’s surrounding. Though the piano installation Keys of Light is accessible for anyone, from beginner to professional, it is always a pleasure hearing and seeing professional pianists taking part in the artwork. During Jerusalem Festival of Light, 2 professional pianists surprised the audience with an immersive performance.


Wandering Lights Festival Tallinn


We visited the beautiful city of Tallinn, Estonia for our participation at it’s three-days Festival of Lights. Wanderling Lights Festival focuses on light and light-based technologies. It creates a platform to meet and share one’s knowledge and experience working with light.

The festival selects artists based on their expertise with light from a scientific and artistic perspective. Keys of Light is a perfect example of an artwork where art and technology are merged into one experience. The festival also offers opportunities to participate in scientific workshops and the experience of light, music, and dance. For us, this was a perfect stage to present another edition of our interactive piano installation.

Kadriorg Palace wandering lights festival


We love to study the history of every location and building we work with, and use it as a source of inspiration. The Kadriorg Palace was another building with a fascination story. This baroque-style palace was built for Catherine I of Russia by Peter the Great in Tallinn, Estonia. Both the Estonian and the German name for the palace actually means “Catherine’s valley”. The palace currently functions as the Kadriorg Art Museum, displaying foreign art from the 16th to 20th centuries.

Light Move Festival Poland


We are privileged to travel to many locations and work with beautiful architecture. The Alexander Nevsky Cathedral in Łódź was one of our favorites to create visual designs for. This orthodox church is located in central Poland and served as our canvas for this edition of Keys of Light.

The Alexander Nevsky Cathedral was built during the period of the Russian Empire with the financial support from the local textile factory owners and the most important citizens. It’s neo-byzantine design resulted in a remarkable octagonal shape. Many characteristic orthodox features of the church inspired us to design visuals that would play with the shapes of the building. We used detailed designs to emphasize the style of clothing and architecture during the Russian Empire. 




Keys of Light always offers a platform for local talent. We love to see how different musicians explore the way music translates into visual language. During this particular festival, Poland showed their multidisciplinary musicians that found their way to the interactive installation.

For the very first time, we had other instruments such as a violin and saxophone accompany the pianist. It was great seeing such participation and creativity emerge. A true treat for the audience to experience performances like this, complemented by projection mapping experience on the beautiful architecture of the Alexander Nevsky Cathedral!
