Funny, I think Star Trek TNG described how the holodeck works by saying that it tricks the user not to walk into the walls. The visual feedback of slowly rotating hallway would definitely overdrive the inner ear. Too much, though, and you're going to get sick from it.

I have quite a few android devices, but the play store tells me that "This app is incompatible with all of your devices". But I'll keep an eye on this, seems nice. I guess it's two-factor enough, because I have a password on my phone.
