Keys of Light

3DLP installed the large-scale interactive projection for Mr.Beam's “Keys of Light” at the tenth Electric Castle festival, held at Bánffy Castle from 17 to 21 July 2024. A piano placed before the castle controlled the mapped architecture in real time: every note generated lines, figures, colour fields and rhythmic pulses across the Gothic Revival central façade, so each visitor created a different performance. The projection kept the responsive artwork vivid against the festival's ambient lighting, joining live music, animation and one of Bonțida's defining historic surfaces.
