I created a VR experience for the company I work at using the Dive plugin for Unity3D. It's called CaseVisor. It has 5 different scenes that recreate spacial exitements such as a skyscraper valley, standing on a cliff or in a open grid space. In the sky you find some air mines, that you can shoot by just looking at them and they explode into many cubes that fall down on you. Visually it's all abstract and cubes and bright colours.
