Resonance

Purple, blue and green projections cover Uppsala Town Hall while people gather around a controller in the square.

Interactive projection mapping on Uppsala Town Hall, where the public could paint the facade in colour.

Resonance was an interactive projection mapping piece on the facade of Uppsala Town Hall. Four weatherproofed touch pads with embedded lighting were placed in the main square, built to handle snow, rain, and countless jumps. I built them with Arduino, feeding into the Unreal Engine project over USB. Each pad triggered a colour ripple across the facade, animating an ocean scene on the building's surface. When all four pads were activated at once, a final sequence of light and music played out. I laser cut a scale model of the building for testing the projection, and the facade was drone-scanned to build a digital replica.
