Matter VR places the participant in a surrealistic virtual environment using an Oculus Rift headset, and allows them to interact with the environment to generate music using Leap Motion hand tracking. I oversaw the art direction of the virtual environment which was inspired by the history and visual aesthetic of the vaporwave music movement, creating moodboards and concept sketches. I then modelled the environment for VR in the Unity3D game engine, as well as scripted different objects in the environment to respond to user-generated music. MatterVR was extensively play-tested with audiences at events such as the Creative Technologists' Meetups and the Auckland Game Developers' Meetups.
