iPhocals

"Take a look at a pair of iPhocals. Proper reading glasses. Download books from an online iBrary via the USB socket on one of its arms (the other houses the rechargeable battery). Press the on/off switch in the frame and pages appear, apparently two feet in front of the lens, in sharp focus. It looks like magic, but it's actually Quasatz Spatial Pseudo Projection. A gentle flick of the head turns the page."
