HUD-tact Lens

From the How-Did-I-Ever-Miss-This Dept:
<blockquote>“Looking through a completed lens, you would see what the display is generating superimposed on the world outside,” said Babak Parviz, a UW assistant professor of electrical engineering. The shape of each tiny component dictates which piece it can attach to, a microfabrication technique known as self-assembly. Capillary forces – the same type of forces that make water move up a plant’s roots, and that cause the edge of a glass of water to curve upward – pull the pieces into position. </blockquote>
