Scientists at IBM have been hard at work on a miniature 3D map of the earth. How miniature? According to their press release, 1,000 of these maps could fit on one grain of salt. The scientists used a new ultra-tiny silicon tip to carve structures as small as 15 nanometers.

Features on the globe include a 25 nanometer 3D replica of the Matterhorn made out of molecular glass. The map was written on polymer measuring 22 by 11 micrometers. It took just 2 minutes and 23 seconds to build. The scientists also managed to etch the IBM logo 400 nanometers deep into silicon.
