The first was ‘Self Frottage with Light’ in which I used TiltBrush, a VR painting app from Google, to manually 3D scan myself. I used the mirror function, intended for making symmetrical drawings, much like a physical world mirror. I sat on the floor in front of it so I could see my body from the outside. In the beginning of the video there is nothing there, nothing to reflect.  My body is invisible. But as I slowly rub the controller over the surface of my skin I become visible in the mirror.
