Perhaps, but Meta has just launched an interesting take on the concept by marrying see-through, stereoscopic, display glasses with a Kinect-style depth sensor.
What our man Pascal Brisset did is design a Linux system around a Gumstix Overo Fire computer-on-module, a Vuzix VR920 head-mounted stereoscopic 640 x 480 display (complete with 3D tilt sensor and 3D magnetic compass), WiFi, and Bluetooth modules -- the whole shebang resides in (and on) the eyewear, just the thing for secure telepresence and augmented reality applications (or just extra-private web browsing).
