Independant R&D engineer and artist, crafting digital instruments for audio/visual live performances, installations and interactive applications. I post some of my works and news on this site.

Wyschnegradsky

Ivan Alexandrovich Wyschnegradsky (Ива́н Алекса́ндрович Вышнегра́дский) was a Russian composer primarily known for his microtonal compositions.

Pascal Criton, a french composer of contemporary music as well as a musicologist who studied Wyschnegradsky’s works, created an interactive piece inspired by Wyschnegradsky’s “ultrachromatic compositions” for association Puce Muse.

I designed a collective instrument able to produce complex polyrhytmic sequences of filtered sound texture. Each step of the sequence can be assigned a color nuance and a pitch, possibly micro-tonal. The result produces visual and sonic moires, reminding of Wyschnegradsky’s chromatic drawings.

You can get it from the Méta-Librairie website.

L’arbre qui cachait la forêt

Sisyphus in the anthropocene hamster-wheel.

L’arbre qui cachait la forêt is a multimedia installation originally proposed for the Festival of Lights of Lyon (FR) happening on december 8th. The theme was about ecology and artists were encouraged to make use of little and/or renewable energy.

The installation consists of an interactive video projection of a tree, with the screen placed precisely where the filmed tree is located. The screen offers a view that corresponds to the perspective of the global environment. In front of this screen, a giant hamster wheel awaits a visitor. The rotation of the wheel causes the video to progress from the current date of the festival, close to the winter solstice, when the tree is apparently dead, to the summer solstice at midday, when the tree is fully green against the deep blue sky. But as soon as the visitor stops running after that desired blue summer sky, the video rewinds to the cold winter night.

Prior to the installation, the tree has been shot with timelapse photography technique during a whole season.

simple timelapse

Simple timelapse is a quick tool to make timelapse movies.

It uses an arduino for setting shutter intervals, an 4N35 opto-coupler to protect the camera from any accidental current, and a led to notify when shutter is in action. Focus was left manual to prevent from any automatic adjustement (that we don’t want anyway for a timelapse) and spare camera battery. Code and circuit was derived from intervaluino borrowing the opto-coupler idea from MaxTech, available at GitHub.

Used for the preparation of l’arbre qui cachait la forêt.

Meta-Screen

Turn a gothic church to a giant pinball.

Meta-Screen was a video mapping project led at Puce Muse, to transform any surface into a projection screen. Developments included tools to quickly map a shape or a contour, as well a real-time algorithm to interact with these shapes, like physics engine to make virtual objects bounce on architectural features.

Meta-Screen is available from Puce Muse’ Meta-Librairie.
