Tilt Brush is Google’s self-proclaimed app for "Painting in 3D space with virtual reality," comes bundled with the headset, and is the first great art app for virtual reality. Using the app and the controllers on systems like the Vive, users can create amazingly detailed artwork. It’s intuitive, intensely immersive, and does something funny… While a user plays around with the different brushes and pencils and zooms, they learn how to use the virtual reality controllers.
The idea of users painting and drawing using the physical space around them wasn’t part of the original mission plan, but something they discovered along the way. According to Hackett, earlier versions of Tilt Brush, although virtual reality, only allowed art to be made on two-dimensional planes. But then "There was a happy accident. Tilt Brush came out of an experiment with a virtual reality chess prototype, where we accidentally started painting the chess pieces in the air, and it was incredible."
