Tilt Brush
Virtual Reality art is fascinating to me, and that's what Tilt Brush is all about. It's a "game" by google but really it's an art program. You draw in the air with different brushes and make whatever you want. I've had a lot of fun with it even though I'm not a great artist. And when you actually watch what a good artist can do with it... it's kind of amazing. I keep coming back to this game. If you end up with a Vive you really need to get this one.
