Create an immersive opening experience for re:publica 2011 that would engage hundreds of attendees simultaneously and set the tone for the three-day conference about digital culture and society.

The installation needed to be visually striking, technically robust, and interactive enough to encourage participation without requiring instructions.

We developed a large-scale projection-mapped installation that responded to audience movement and sound in real-time. Using motion sensors and audio input, the system generated evolving visual patterns that reflected the energy and density of the crowd.

The visual language drew from data visualization principles—transforming abstract inputs into flowing, organic forms that felt both technological and human. Color gradients shifted based on ambient audio frequency analysis.

Technical implementation used Processing for real-time graphics generation, with custom OSC bridges connecting sensor data to visual parameters. The system ran on redundant hardware to ensure stability during the live event.

The installation successfully engaged over 500 attendees during the opening session. Audience members naturally experimented with the system, creating emergent choreographies as they discovered how their movements affected the visuals.

The project demonstrated how large-scale interactive experiences can create shared moments without requiring explicit instruction—the system's responsiveness was intuitive enough to encourage exploration.
