Rebus Cumulations Press



Depart creates a permanent audiovisual installation at the new SoundCloud HQ in Berlin.

Vienna based Depart (Leonhard Lass and Gregor Ladenhauf) were commissioned by SoundCloud to create a new audiovisual piece for permanent installation in their new HQ office building in Berlin.

With their artwork “Rebus Cumulations” Depart have created a mixed media clockwork system – a mesmerizing triptych of video screens, real time generated graphics and sound. The centerpiece is a visualisation of global, up-to-the-minute SoundCloud usage data and the two wing pieces show an accompanying, neverending flow of poetic still life video loops.

These surreal moments, so called cinemagraphs, seemingly frozen but parts of it moving at the same time, are also host of an automated poetry generator that creates a new commentary or title sentence for each cycle of data tendency evaluation.

It combines abstract data visualisation and cinemagraphic still lifes into an enigmatic alchemy of objects, sounds and language – Constantly changing and balancing on the sweetspot between the mundane and the surreal.


Realtime Triptych

 120 still lifes – Thing-based poetry

We arranged and filmed about 120 still lifes, structured into 5 categories based on their activity/movements: dissolving, rotating, oscillating, streaming, accumulating. Those qualities are used to relate them to the activity in the data. So for instance a decline in SoundCloud plays and uploads produces a “dissolving” still life, whereas a constant development would display a “flowing” movement.

Realtime datasculpture and clockwork

The centerpiece is a data entity that represents the rhythm and energy of the system and is driven by global realtime data from SoundCloud .

We analyse global SoundCloud plays, uploads and favorites per minute and translate it into a organic data sculpture. Every new upload creates an instant event and the data visualisation represents this activity.


Generative poetic system

Every single object (around 1200) in the ~120 still lifes is cataloged and crosslinked within lexical databases of associations. Whenever a new scene appears object pairs are iterated and a new poem is generated based on their related meanings.


Constantly changing

Determined by graphical rules, the arrangement is constantly changing.


The application was developed with VVVV. It runs in realtime and is connected to SoundCloud usage statistics (webservices and UDP endpoints). Every minute the global data set is analysed and according to detected tendencies a “energy state” is calculated which drives the whole system and decides the dramaturgy.

The installation is presented on three FullHD 46″ LED screens, custom made speakers and built into a wooden box (280cm x 160cm x 40cm).



The sound is generated in NI Reaktor and synced to the control structure and visuals via OSC.
