Concert For A Sustainable Planet

A visual that accompanied a choir, singing a piece by Merlijn Twaalfhoven. Performed in Carnegie Hall, New York (2017).

The visuals are generated by custom-made software, developed by Jildert Viet, that reacts to the musical score.
The software reverse-engineers the composition, by translating pitches back to relative temperature data.
This data influences a 3D landscape, which unfolds with time.
Sung notes are visible on the landscape as temperaturedata-nodes. Every voice is distributed on the x-axis.
When higher temperatures (/notes) emerge, the peakyness and movement of the landscape increases, which gives it a more unstable state.
The last 20 temperatures are kept in memory, and the average determines the actual height-, peakyness- and movement-values.
This way the rising pitch of the score gives the visual a uneasy feeling, according to the theme.

Dynamic Heights / Canvas

Dynamic Heights is a 1 minute video generated by custom software.
Geometry is calculated by recursive divisions, meaning that each new shape relates to the previous existing ones. After the initial geometry is created the system starts moving, all shapes react to each other and fit their sizes to their neighbours. The program has the dimensions of the Canvas-installation as an input and generates a complex 3D-model per frame. These models are then rendered by a photorealistic path-tracing engine. The obtained lights and shadows emphasizes the geometry.
The video was on regular display at Tivoli Vredenburg, Utrecht.


LCD has been developed for the Grasnapolsky festival in 2020.
As expected, the LCD screens plays a central role in this audiovisuals installation. This mass produced technology is all around us, and therefore it was easy to collect around 30 monitors. These monitors are stripped and modified into individual, WiFi controlled, video synthesizers. All together they form a live instrument, which plays an endless algorithmic AV piece during the 3-day exhibit.
