I want VR, but not Oculus because of the FB linkage (I don't have FB). I also want it to be self-contained, so I don't need a fancy PC to run it, but it should still connect to my PC as a display device or something. I also want it to be open source, or at the very least it should not have telemetry, account logins, or anything like that for the hardware. It also has to work on any OS, it should work with my game consoles, and my TV output as a virtual screen. I just want a "dumb" VR display, effectively. An AR display would be nice, too, if I could put a "mask" over it to turn it into a VR display. Right now, I am pretty sure there is nothing to fit that bill. If there is in the future, I definitely want this, if only to be able to play games while lying in bed or to have several virtual computer screens for coding and work.
