This two-part installation at the Guinness Storehouse museum in Dublin combined sculptural lighting and large-scale projection mapping to create a unique and immersive holiday experience. The first element was a dramatic light sculpture suspended on the third story of the central atrium. Composed of hundreds of vintage-style light bulbs arranged on a steel frame, the piece revealed the iconic Guinness harp when viewed from a specific angle. Each bulb was individually addressable, enabling synchronized light chases and dynamic patterns that responded to accompanying sound effects. The second installation was a two-story Christmas tree built from stacked white cubes. We projection-mapped festive animated content onto the entire structure using 20 high-powered projectors. For this, we collaborated with the team behind Screenberry, who flew in from Ukraine to assist with calibration and playback across the complex projection surface. I played a key technical role across both parts of the project. I built and configured the control servers, integrated over 50 light bulb controllers, and created automation and scheduling systems to allow for reliable, un-manned operation. I also assisted in the full projector setup and alignment, and used MadMapper to map video content onto the bulb sculpture with spatial accuracy.
