Kingspray Graffiti Simulator is the sort of app that will make people buy a VR headset. With the HTC Vive, a user is able to step into a very real-looking virtual space. The user is given a can of spray paint and an open canvas. Not a traditional canvas, mind you - a wall on a rooftop. Or a train car. Or a billboard. You, the user, play the part of a street artist, and you've got free reign over your virtual - real - world. You're gonna be a belieVR.
