Google's Tilt Brush is a light painting app for the HTC Vive (reviewed here), and now you can incorporate 360 photos into your Tilt Brush art thanks to Nick Lievendag. Nick made a utility that allows you to add a 360 photo as background for Tilt Brush image. He did it by creating a 3D sphere and then made it easy to replace the texture of the sphere with a 360 photo. Ingenious! Check out Nick's page, which has the download link and more detailed instructions.
