Google has created a virtual reality app called Tilt Brush that allows artists to paint in 3D space, creating immersive artwork and colorful landscapes that spectators can not only view, but explore. The Tilt Brush, which is available on the HTC Vive headset, lets artists create 3D works with simple controllers instead of paint brushes and a virtual color palette instead of paint. The app liberates painting from the two-dimensional canvas, allowing artists to create works that occupy three-dimensional (albeit virtual) space.
