Sony's new HMZ-T1 headset may look like the virtual reality headset you always dreamed of back in the 1990s, but it's not -- at least, not out of the box. It's simply a wearable 3D display, with none of the head-tracking capabilities necessary for a truly immersive experience. Of course, that little drawback isn't going to stop the more DIY-minded individuals among us, one of whom has now paired the headset with a TrackIR 5 head-tracking device and demonstrated the results on YouTube. Check out some VR-ified World of Warcraft and Skyrim after the break.
