I'm a little nauseous and a bit sweaty. This was my first time using the Oculus Rift. It's the sort of thing you've got to ease into, really -- sitting stationary, letting your brain adjust to the whole experience. Or you could just pop the thing on and run in place on a treadmill in a downtown Los Angeles hotel suite. Your call, really. Just don't come crying to me when you're having a bit of trouble standing up straight, as you attempt to step down from the slippery surface at the end of your session.
