Drew Skillman and Dan Hackett, two former video game developers from San Francisco, have turned an accidental bug from an early  VR experiment into one of the most compelling pieces of software available for any VR platform. In fact, the software was so compelling that Google came calling, and now Skillman and Hackett are working internally for the behemoth. Now, with the support of Google behind them, they have been able to attract a team of additional developers to the project. The software has slowly morphed into the most sophisticated VR tool for drawing, painting and sculpting in 3D space. If you have any creative bones in your body, you simply have to give Tilt Brush a try.
