It was only a matter of time before someone took advantage of the SteamVR interface and brought in a more interactive, and familiar, background. Surreal nature or space photos are great, but didn't we invent VR as a stopgap to a full-on holodeck?
The SteamVR interface allows you to interact completely inside the headset, and you've got the option of changing the grid background to something more pleasing, such as a 360-degree view of London, or New York, or even the Milky Way. But why wouldn't you want to recreate something more iconic and appropriate to the technology. Now all we need is a way to create a shimmering effect into your game as it loads.
The holodeck is nothing more than the usual black backdrop with yellow markers, but it's the simplicity that makes it so fun, that's what the holodeck is, after all. You can experience it yourself if you have any sort of VR device that's compatible with Steam, right here.
