Silicon Micro Display ST1080
If you like watching 1080p video, but you don't like being tied down to a screen, you can pick up Silicon Micro Display's ST1080 wearable display ($799). This large, wearable display shows you the equivalent of a 100-inch display at a distance of 10 feet. It supports 2D and 3D content, and it features 10 percent transparency (so you can walk around without running into walls). It comes with 3.5mm mono headphone jacks on either side, and comes with a small controller box that can connect to anything with an HDMI output.
