The smallest henge?

minihenge

Scientists at the National University of Singapore, testing out a process called silicon micromachining, chose to make this Stonehenge microstructure with a proton beam writer. “The proton beam writer, housed at the NUS Centre for Ion Beam Applications, can focus proton beams to diameters of less than 50 nanometres (about 2,000th the diameter of a human hair).” Why they chose to make a Stonehenge replica is not mentioned on the site, but we’re glad they did!

This pseudo-Stonehenge, created on a silicon wafer, gets our highest score yet: 8 druids!
