3D projection mapping is a technology that uses objects as surfaces. It turns the object into a 3D model, making it an interactive display. This technology is used widely by advertisers and artists on buildings and stages.
The Eloi's projection is made in real-time with real-life sound, mouse, and keyboard in order to create a variety of effects. For the warping, he used Immersive Display Pro. Shaders in the projection are from Mads Drøschler. You can get the shaders on Github.
Eloi also made a 3D mapping tutorial that you can watch here.
