Infineon Technologies' Lim Saw Sing discovered a colony of microscopic nudists having an orgy on the surface of an integrated circuit. Of course, there is some chance, albeit small, that they aren't nudists but rather just the polyimide surface itself after being exposed to etching by reactive ions. In any case, the image took a top prize at the 2012 IEEE International Symposium on the Physical and Failure Analysis of Integrated Circuits.
