OPUS was a VR experience combining Oculus rift and Leap motion technologies. Inspired by block games such as Tetris or Lego, it was a mesmerizing experience which brought people into another dimension. Opus was offered a digital journey from a structured and tidy environment to a restructured and chaotic world. Colors, volumes and space are constantly redefined all along the experience by the user's actions. The experience was driven by a balance between creation and destruction where the music immerses players into a world which is neither ruled by time, score or ending. Surrounded by giant shapes looking like toys, the goal was to make the user feel like they were in the middle of their childhood playthings.
