Thanks to a bunch of smartypants at the Vienna University of Technology, some of the world's most impressive architectural achievements have been shrunken to the size of a grain of sand. According to Geek.com, researchers created "a system whereby a laser is directed by a series of mirrors through a liquid resin which then hits a surface and leaves behind a polymerized line of solid polymer. The thickness of that line is just a few hundred nanometers." Translation: an ultra-precise, ultra-fast 3D printer makes nanoscale models, like the Lilliputian version of Vienna's St. Stephen's Cathedral above. And that's no small feat.
