– – – is a 12 minute audiovisual composition consisting of three vertical projections, placed side by side with a small space in between them. At the core of this work is a programme I constructed in openFrameworks (an open source C++ toolkit), based on found code, which simulates the interference patterns of waves. The simulation manifests itself in both sound and image. With this I mean that parts of the simulation are represented in two different media.
The simulation runs in real-time and can be ‘played’ using a physical midi-controller. Modifying multiple parameters simultaneously with physical knobs allows, to my idea, a faster and more complex interaction with the software than simply using a GUI (graphical user interface). This relates to an instrumental practise. Of these ‘played interactions’ with the interference patterns, I made short screen and audio recordings.
The two representations in sound and image of the recordings of the interference patterns are then composed together over the three projectors in time. In this composition the two media are not always synced, but are made from the same recorded material, and could be seen as two layers which interact with each other. The three vertical projections often show the same process but at varying speeds and camera angles. Decisions regarding the overall structure and order of the sequences is based on a narrative of perspective (camera angle). Here are some excerpts:
