I just had a great thought that you could capitalize on! All of your landscapes are rendered in 3D, so what if you could find a way to sell a copy of one to someone likes it? You could have it sync up with the Oculus gaming headset and they could wander through your worlds in relaxing bliss.
This is just an idea I wanted to share. I'm urging you to do it, and if you find a way to I'm not gonna come back and demand profit. Do with it what you like.
