OP_ERA: SONIC DIMENSION is an immersive *virtual reality* installation designed as a music box. In its United States premier, the Beall Center for Art and Technology at UC Irvine is pleased to present this award-winning interactive art exhibition from Brazil. Entering into the 10’x13’ enclosure, the open cube is filled with hundreds of visually identical violin-like strings. Using Pythagorean principles, OP_ERA lets you embody one of physics’ most complex phenomena.
